Centimeters to Feet Converter

feet = centimeters ÷ 30.48

Example: 180 cm × 0.0328084 = 5.91 ft. To convert back, multiply ft by 30.48.

Ask somebody in Germany, Japan, or Brazil how tall they are and you get a centimeter number — 170 cm, 184 cm. Ask the same question in the US and you get 5'7", 6'1". Almost every height that crosses between those two worlds has to be translated: the NBA scouting report next to the FIBA roster, the pediatric growth chart pinned to the exam table, the medical form that wants inches while your passport says centimeters, the IKEA wardrobe spec sheet that measures in cm while your American ceiling was built in feet. The trap is that the division gives you decimal feet — 170 cm comes out as 5.58, which is 5 feet and some leftover, not 5 feet 58. The leftover gets multiplied by 12 to become inches: 170 cm is 5'7", exactly. The converter above does that second step automatically and works in both directions; the sections below go through the numbers people actually search for, where the conversion decides real outcomes, and how to do it in your head well enough to trust.

Type into either box and the other updates as you type. Put 170 into the centimeters box and the feet box shows 5.58 — that's decimal feet, the raw division result, not a height anybody says out loud. The feet-and-inches answer (5'7") is calculated underneath it, so you don't have to do the leftover-times-twelve step yourself. It also runs backwards: if an American form says 6'2" and you need to know what that is in centimeters for a visa application, type 6.1667 (6 and 2/12 feet) into the feet box and read off 188. The quick-reference table below covers 150 to 190 cm in 5 cm steps, which brackets most adult heights people look up; anything outside that range works exactly the same, because the formula never changes.

One honest caveat about the decimal feet display: a lot of people see 5.58 and write "5.58 feet" on a form, which a form designed for feet-and-inches will misread. If you need the inches, use the feet-and-inches line, not the decimal one. If you're converting for something that genuinely wants decimal feet — some engineering and aviation contexts do — then the decimal display is exactly right. The two answers describe the same height; they're just written for different readers.

170 cm is probably the single most-converted height on the internet, and it deserves a careful answer. 170 ÷ 30.48 = 5.5774 feet. The 0.5774 is the part past 5 feet, and multiplying it by 12 gives 6.93 inches. So 170 cm is 5'6.93" — one seven-hundredths of an inch shy of 5'7", which everyone rounds to 5'7". What makes 170 pleasant is how close it lands to a clean number; most centimeter heights don't. 173 cm is 5'8.11", 171 cm is 5'7.32", and 169 cm is 5'6.54" — those fractional inches are why people convert the same height repeatedly, hoping a different tool will give them a tidier answer. It won't. The tidy ones are rare and worth memorizing.

The anchors that cover almost every real situation: 150 cm is 4'11", 160 cm is 5'3", 165 cm is 5'5", 170 cm is 5'7", 175 cm is 5'9", 180 cm is 5'11", 185 cm is 6'1", 190 cm is 6'3". There's a pattern hiding in that list — 5 cm is almost exactly 2 inches (it's 1.97), so once you know one anchor you can walk the whole ladder two inches at a time. Someone tells you they're 178 cm? Start at 175 (5'9") and the extra 3 cm is a bit over an inch, so 5'10". Someone's 162 cm? Start at 160 (5'3") plus 2 cm, call it 5'4". That single fact — 5 cm ≈ 2 inches — does more conversion work than any formula you'll memorize.

For the reverse direction, feet-to-cm has its own page here with the same anchors running the other way, and if the height you're working with is under 150 cm or you're dealing with a baby's length in inches, the inches-to-cm converter handles the small measurements more naturally than this one does. Whole feet and nothing else converts cleanly here: 5 feet is exactly 152.4 cm, 6 feet is 182.9 cm, and there's a dedicated feet-to-cm page for when the input is already in feet and inches.

Basketball is the most public cm-to-feet battleground there is, because the NBA measures in feet-and-inches while FIBA and every European league measure in centimeters, and the same players appear in both. Yao Ming was listed at 7'6", which is 228.6 cm — a number Chinese media reported as 2.26 m or 229 cm, depending on the outlet, because his barefoot height and his shoe-wearing measurement never agreed. Muggsy Bogues, the shortest player in NBA history, was listed at 5'3" — 160 cm — and played 14 seasons in a league where the average man is 6'6" (198 cm). The spread between those two is over two feet, and both played the same position at different times.

The listed heights are not always the truth, and the conversions expose that. Kevin Durant has said publicly that he's about 6'11" (211 cm) barefoot but prefers being listed at 6'10" (208 cm) — players near seven feet often shave an inch off the roster sheet because "7-footer" carries expectations. Draymond Green has admitted to being listed shorter than he measures, the opposite move, because a 6'7" listed forward who plays center looks scrappier in the scouting report. Steph Curry is listed at 6'2", which is 188 cm, though pre-draft measurements without shoes put him closer to 6'1.5" (187 cm). Isaiah Thomas, listed 5'9" — 175.3 cm, the exact US male average — was the shortest All-Star in decades, and American coverage of him never once printed his centimeters while European coverage of the same games never printed anything else.

If you follow international basketball, the conversion goes the other way constantly. Luka Dončić is listed 201 cm by EuroLeague sources and 6'7" by NBA ones — 201 cm is 6'7.15", so both are the same fact. Victor Wembanyama is 224 cm (7'4.4"), and the American media rounded him to 7'4" while French media wrote 2.24 m. Giannis Antetokounmpo measures around 211 cm (6'11") in shoes. Nikola Jokić is 211 cm too — 6'11" — though a lot of American broadcasts just say "seven feet" because 211 is close enough to 213.2 that nobody complains. That's the last thing worth knowing here: once heights get big, the two systems tolerate rounding differently. A 1 cm error on a 170 cm person is invisible; a 1 cm error on a 224 cm prospect is the difference between two different draft profiles.

Medical paperwork is where this conversion stops being small talk. A routine physical in the US asks for height in feet-and-inches on the intake sheet, then the nurse measures you and the chart records it in inches — 69, for someone who is 5'9". But the dosage calculations that ride on top of that height run on metric: pediatric dosing, chemotherapy protocols, and the Mosteller body-surface-area formula all take height in centimeters. So the same visit contains both numbers, converted in the background by software that assumed the front desk typed them correctly. If the intake form got 5'6" instead of 5'9", every metric number downstream is off by about 7 cm's worth of body surface, and nothing flags it.

Pediatric growth charts split the two systems along an organizational line. WHO charts, used nearly everywhere outside North America, are drawn in centimeters; the CDC charts common in US clinics run in inches. A parent moving from Berlin to Chicago with a 96 cm three-year-old has to know that's 37.8 inches before the American chart means anything — and the pediatrician's front desk will happily do it, but only if the parent knows to ask. School physicals, sports clearance forms, and camp medical sheets each pick their own unit, sometimes within the same packet.

A few specific form facts worth having. US driver's licenses record height in feet-and-inches, except in states like Michigan that print total inches only — a 5'9" applicant's card shows "69" with no unit at all, which confuses anyone reading it from a metric country. FAA medical certificates ask for inches. US Army enlistment historically required height between 60 and 80 inches — 152.4 to 203.2 cm — a range that excludes almost nobody but is still checked. Flight attendant requirements at several airlines are written as a standing-reach number in centimeters, often 212 cm, which American candidates have to translate from their own reach to know if they qualify. And visa forms for metric countries want centimeters from applicants who have known themselves in feet for forty years — 5'10" is (5 × 30.48) + (10 × 2.54) = 177.8 cm, and writing "178" on the form is the expected move.

Theme parks are the place where a centimeter-to-inch mistake has a hard stop at the measuring stick. US parks post ride restrictions in inches: 48 inches (122 cm) is the classic big-coaster threshold at parks like Cedar Point and Six Flags, 54 inches (137 cm) gates the tallest rides such as Kingda Ka at Six Flags Great Adventure, and Disney's family coasters typically sit at 38 to 44 inches (97 to 112 cm). European parks write the same rules in centimeters — Europa-Park and Alton Towers-style signs read 120 cm, 130 cm, 140 cm — and a family traveling between them is converting at the ride entrance with a kid watching.

The trap is that the two systems' standard thresholds don't line up on round numbers. A child who clears 48 inches at a US park (121.9 cm exactly) is fine at a European ride gated at 120 cm, but a child at 118 cm passes nothing in Europe and clears several 46-inch (117 cm) rides in the US. Three centimeters is the difference between a family riding together and one parent sitting out, which is why the measuring boards exist at every entrance rather than just the ticket window. If you're planning a trip across systems, convert your kid's current height — children grow fast enough that last summer's number is stale — and check each park's published limits rather than assuming they match.

The same logic runs through ski rentals (kid skis sized in cm in Europe, inches nowhere), stroller size limits on airlines (some in cm, some in inches, both on the same gate sign), and trampoline park waivers. Wherever a child's body meets a hard safety threshold, the threshold is written in whatever unit the country grew up with, and the family is the one doing the math.

IKEA is a Swedish company that publishes dimensions in centimeters everywhere on earth, and that's fine until the furniture arrives at an American apartment built to imperial specs. A PAX wardrobe frame is 79¼ inches tall — 201.1 cm, though the US site writes it as 79 and a quarter inches — and the room it has to stand in has a ceiling that was framed at 96 inches nominal, which after flooring and framing realities is closer to 94 or 95 real inches. It fits, usually, but the spec sheet never tells you that, because the spec sheet assumes you measured your ceiling. A BILLY bookcase is 79½ inches (202 cm) tall and 11 inches deep; a MALM bed frame sits about 9 inches high without a mattress. None of those numbers are round in the other system, which is the whole point: the product was designed in centimeters and the inches are a translation, not a design choice.

Doors are the sharpest version of this. An American interior door is 80 inches — 203.2 cm — and a European door runs 198 to 210 cm depending on the country. Move furniture made for one market into the other's housing stock and you find out fast: a 210 cm French door frame won't fit in a US rental, and a 201 cm German wardrobe leans dangerously close to an American 203 cm doorway's trim, which eats another 2 cm on each side. Renters comparing listings across countries are doing this math with a deposit on the line — "9 ft ceilings" in a New York listing is 274 cm, "hauteur sous plafond 2,60 m" in a Paris one is 260 cm, and that 14 cm decides whether the loft bed the previous tenant loved will physically assemble.

Kitchens disagree too: US counters are built at 36 inches (91.4 cm) while European standard is 85 to 90 cm, so an American standing at a Dutch kitchen island feels like everything dropped an inch and a half — because it did. The general rule for furniture across systems is the same as for anything else: convert every dimension explicitly before you buy, never eyeball it, and remember that doorway trim, baseboards, and light fixtures all steal clearance that the raw ceiling-height number promised you.

The split isn't random — it's a map of who standardized when. Most of the world adopted the metric system in the 19th and 20th centuries, and height went metric with everything else. The US passed the Metric Conversion Act in 1975 but made it voluntary, and nothing forced the switch, so feet and inches stayed in construction, clothing, and how people describe their own bodies — while science, medicine, and the military quietly ran metric underneath. The 1999 loss of the Mars Climate Orbiter, destroyed because one team used pound-force units and another used newtons, is the famous price tag on that ambiguity.

The interesting cases are the countries in between, because hardly anybody is purely one system. The UK measures height in feet-and-inches and weight in stones, buys fuel in liters, and drives in miles — four different answers depending on what you're measuring. Canada officially went metric in the 1970s, so documents say 178 cm, but plenty of Canadians still describe themselves as 5'10" and real-estate listings quote square feet. Australia and New Zealand converted thoroughly and now use centimeters almost exclusively. India officially uses centimeters but colloquial height talk splits by generation and region. Japan is metric throughout. So when you meet someone who "can't" convert their height, the real question is which of these systems they grew up inside — a Brit and an American can talk height freely, and both will be lost talking to an Australian who just says 183.

The inch itself has been legally fixed at 2.54 cm since 1959, when the US, UK, Canada, Australia, New Zealand, and South Africa agreed on one definition — before that, the US inch and the imperial inch differed by a few parts per million, which mattered to machinists if not to anyone describing their own height. Every conversion on this page rests on that agreement, and on the foot being defined as exactly 30.48 cm, which is why the numbers never drift between sources.

The trick that survives real conversations: 5 feet is 152.4 cm, call it 152. Take the centimeters, subtract 152, divide what's left by 2.5, and you have the inches past five feet. Somebody says they're 178 cm: 178 − 152 = 26, and 26 ÷ 2.5 ≈ 10.4, so 5'10". Someone's 165 cm: 13 ÷ 2.5 ≈ 5.2, so 5'5". Both land within a fraction of an inch of the exact answer, and you can run it while the other person is still mid-sentence.

For heights below 152 cm, flip it: subtract from 152 instead. A 137 cm child is 15 cm under five feet, and 15 ÷ 2.5 = 6, so 4'6". A 120 cm kid is 32 under, 32 ÷ 2.5 ≈ 12.8, so about 3'11" — which is why so many theme park thresholds cluster in the high 30s of inches, as the ride section above showed. If you only need a feet-only ballpark, divide by 30 and shave about 1.5%: 180 ÷ 30 = 6, minus roughly 0.09, gives 5.9 decimal feet — which, remember, is 5'11", not 5'9". The divide-by-30 shortcut runs slightly high because a real foot is 30.48 cm, and that 1.6% is exactly the gap people trip over.

When you don't want to trust mental math — a form, a medical record, an official application — use the calculator at the top of this page instead. It handles both directions and the decimal-feet-to-inches step, which is where hand calculations most often go quietly wrong.

First, and by a distance the most common: reading decimal feet as feet-and-inches. 5.9 feet is 5'11", not 5'9" — the 0.9 is nine-tenths of a foot, and a tenth of a foot is 1.2 inches, not 1 inch. Every decimal-feet number needs the leftover multiplied by 12 before it means anything to a human. This mistake moves a stated height by two inches in either direction and it looks completely plausible on the page, which is why it survives into medical records and ID documents.

Second, spreadsheet notation. Someone types 5.11 meaning "five foot eleven" and every piece of software reads it as 5.11 decimal feet, which is 5'1.3" — a ten-inch error that no validation catches because the number is a legal number. The boring fix is to store height as inches only (71) or centimeters only (180) and format it for humans at display time. Mixed-unit columns in a spreadsheet are how a 6'5" row becomes a 5'5" row three exports later, and nobody notices until a jersey doesn't fit.

Third, rounding toward the flattering number. 179 cm is 5'10.47" — it rounds to 5'10" honestly, but it gets written as 5'11" often enough that self-reported height databases run measurably hot. On a passport or a commercial driver's medical card, nearest-inch is the rule and it does get checked. Everywhere else the enforcement is your conscience and the half-inch you were about to invent. If you're converting a number you plan to write down and defend — on any form — the calculator above gives you the unrounded answer and lets you do the rounding on purpose.

Clothing size charts in North America and Europe use different primary units but end up encoding the same breakpoints. A men's size-L shirt at a U.S. retailer lists the fit model as 6'1" (185 cm); the European equivalent says 185/92, where 185 is centimeters from floor to crown. Once you know that 180 cm = 5'11" and 185 cm = 6'1", the size ladder snaps into focus: each 5 cm step is almost exactly 2 inches, which is why international size charts are laid out in 5 cm increments. The 178 cm mark deserves special attention: American sizing rounds it to 5'10", but some European slim-cut brands use 178 as the hard cutoff for a "regular" inseam versus a "long." If you've bought jeans that looked right online and arrived 2 inches short, that's often the reason — the retailer was converting 178 cm to 5'10" and you are actually 5'10.4", which maps to the next inseam tier.

Furniture clearance follows a parallel logic. A standard kitchen countertop in the United States is 36 inches high (91.4 cm), designed for a person standing between 5'4" (163 cm) and 5'10" (178 cm). The ergonomic recommendation is that your elbow should clear the counter by 2–4 inches when relaxed. If your height in centimeters is above 185, standard counter height will make you hunch; if it's below 160 cm, you'll be reaching up. European kitchen fitters quote counter heights in centimeters and typically offer 85, 90, or 95 cm as options — knowing your height in cm makes that conversation immediate rather than requiring a conversion step. Desk height follows the same breakpoints: the 71–76 cm adjustment range of most sit-stand desks maps to roughly 5'4" through 6'2" (163–188 cm). Our /feet-to-cm page handles the reverse trip if you're starting from a height in feet.

The CDC growth charts used in American pediatric clinics measure length or height in centimeters and then convert to inches for the printed label — but the percentile lines are calculated in centimeters. A 2-year-old boy at 88 cm is at the 50th percentile; if the nurse records 34.6 inches (the 88 cm conversion) and a rounding error gives 35 inches, the chart places him at roughly the 55th percentile. That's a 5-point percentile shift from a half-inch documentation error. The WHO Multicentre Growth Reference Study, which sets global benchmarks, publishes all reference data in centimeters precisely to avoid this rounding cascade. For parents tracking a child's growth at home, measuring in centimeters and converting via a tool like this one when needed — rather than trying to read a height board calibrated in quarter-inches — reduces the error introduced at the measurement step itself.

Pediatric height-for-age also surfaces a common parent mistake when estimating adult height from growth charts: parents read the projected 50th-percentile height at age 18 in the unit printed on the axis, which in U.S. charts is often inches, then mentally translate it as centimeters. A projected adult height of 70 inches (177.8 cm) is 5'10", not 70 cm (which would be 2'3"). The error is obvious when stated plainly, but it appears consistently in parenting forums and is a documented category of call to advice nurses. If you're reading a growth chart and want to cross-check the projected height in centimeters, the /inches-to-cm page handles that direction. The clinical rule is simple: always note the unit printed on the axis before reading the value, and verify any number that seems wildly outside the range of normal adult heights.

Surveying, civil engineering, and some aviation documents use decimal feet — not feet-and-inches — as their native format. In U.S. land surveying, elevations are recorded to hundredths of a foot: a benchmark at 312.47 feet means 312 feet and 0.47 × 12 = 5.6 inches above mean sea level. No engineer writes 312'5.6" in a survey report; the decimal form is the standard, and software reads it that way. ICAO aerodrome charts list obstacle heights and runway elevations in feet, almost always in decimal form. When an airport publishes a runway threshold crossing height of 55.3 feet, that 0.3 is three-tenths of a foot — 3.6 inches — not 3 inches. Using a calculator that returns only feet-and-inches for these contexts produces a number the engineering software cannot accept without manual re-entry.

The conversion from centimeters to decimal feet is a single division: divide by 30.48. That's it — no splitting into a remainder, no second multiplication step. The calculator on this page shows both the decimal result and the feet-and-inches breakdown, so if you're working in a context that wants decimal feet, you use the top line; if you need feet-and-inches for a garment, a form, or a conversation, you use the breakdown. If a colleague hands you a number in decimal feet and you want centimeters to cross-check it, our /feet-to-cm page accepts decimals directly and runs the arithmetic in the other direction. The practical upshot: 5.58 feet is the correct answer for a surveying spreadsheet, and 5'7" is the correct answer for a visa form, and neither is wrong — they just have different readers.

Every international visa application that asks for height expects a specific unit — and which unit depends entirely on the country issuing the form. The U.S. DS-160 nonimmigrant visa form asks for height in feet and inches, with separate boxes for each. The UK Standard Visitor visa form asks for height in centimeters. Canada's IMM 1294 asks for height in centimeters. Australia's 1419 uses centimeters. If you are 178 cm tall and fill out the U.S. DS-160 height field with "178," a consular officer reading 178 feet would flag the application for data review; the form validation software may reject it outright as out-of-range. The correct entry for a 178 cm person on a U.S. form is 5 feet 10 inches — not 5.84 feet (the decimal output), not 70 inches (the total-inches-only figure). Separating feet from the remaining inches is the step most people skip when they convert cm to feet and inches for official documents.

The downstream risk is document inconsistency. Your passport lists height as 178 cm (the Australian or European standard). Your U.S. visa lists 5'10". A border officer comparing the two documents knows they match, because 178 cm and 5'10" are equivalent to within less than a centimeter. But if you entered 5'9" by rounding 178 cm down rather than to the nearest inch, the two records now disagree by 2.54 cm — small, but enough to prompt a second look. The safest approach: convert cm to feet and inches using a precise calculator (this page does that; the feet-and-inches line is the one to copy), round to the nearest whole inch only at the final step, and write the same converted value consistently across every form in the application set. Our /cm-to-inches page shows the total-inches figure, which is what some older U.S. medical forms request instead of the feet-and-inches format.

Furniture and building materials sold in the United States carry imperial measurements; the same product sold in Europe carries metric ones. A 96-inch IKEA PAX wardrobe is 243.8 cm tall — IKEA's own product page shows both because it ships globally. A standard U.S. interior door opening is 6'8" (203.2 cm), a figure that almost never appears on the door itself but shows up in every framing diagram. When you buy a door in Europe and import it, you have a door height in centimeters and a rough opening in feet-and-inches, and converting cm to feet accurately is the difference between a door that fits and one that has to be trimmed. 200 cm is 6'6.74" — 1.26 inches short of the standard U.S. rough opening, which means a 200 cm door will leave an inch-and-a-quarter gap that requires a filler strip or a non-standard header.

The same issue appears on a smaller scale with ceiling heights and light fixtures. A pendant light described as "100 cm drop" hangs 3'3.4" below the ceiling — whether that clears a 7-foot (213.4 cm) ceiling over a dining table depends on whether the chairs seat people at 90 cm (35.4 inches) or taller. Designers working in both unit systems typically keep a reference card with the four most common ceiling heights: 8 ft (243.8 cm), 9 ft (274.3 cm), 10 ft (304.8 cm), and 12 ft (365.8 cm). For flooring and tile, convert cm to feet and then take the square footage: a 400 × 600 cm room is 13.12 × 19.69 feet = 258.3 square feet, and you would order tile in that unit if the distributor quotes by the square foot. Converting via /meters-to-feet first keeps the numbers manageable for room-scale measurements.

Medical and athletic records sometimes use fractional inches: 5'10½", 6'1¼", 5'9¾". Converting these to centimeters — or back from centimeters — requires handling the fraction correctly before multiplying. The half-inch in 5'10½" is 0.5 inches, which is 1.27 cm. So 5'10½" = (5 × 30.48) + (10.5 × 2.54) = 152.4 + 26.67 = 179.07 cm, not the 177.8 cm you would get by ignoring the half-inch and converting 5'10" flat. That 1.27 cm difference is small in everyday conversation but meaningful in clinical records, where a patient measured at 179 cm on one visit and 177.8 cm on the next might trigger a note about apparent height loss.

The reverse direction — converting 179 cm back to feet-and-inches with a fraction — works like this: 179 ÷ 30.48 = 5.8727 feet. Subtract 5 and multiply the remainder by 12: 0.8727 × 12 = 10.47 inches. So 179 cm is 5'10.47", which rounds to 5'10½" to the nearest quarter-inch. The quarter-inch standard is used in custom garment sizing; the nearest half-inch standard appears in U.S. athletic records; the nearest whole inch appears on most identity documents. Knowing which rounding step to apply prevents the situation where you convert 178 cm on a visa form to feet and get 5'10.08", then round to 5'10" for the form, but the sports database rounds to 5'10" too — and your listed height on both records looks identical even though one input was 178 and the other was 179. The convert cm to feet and inches calculator on this page shows the decimal fraction so you can apply the correct rounding standard for your context. If the source height was in inches with a fraction, the /cm-to-inches page handles the reverse trip without requiring you to split feet and inches first.

U.S. pediatric growth charts from the CDC come in two versions: one with stature in centimeters (the metric chart, typically used in clinical settings) and one with stature in inches (the customary chart, often handed to parents). The 50th-percentile height for an 18-year-old male on the CDC chart is approximately 177 cm or 69.7 inches. A parent reading the metric chart sees 177 and translates that as a height in the range of normal — because 177 is a plausible adult height in centimeters. A parent reading the inches chart sees 69.7 and should translate that to 5'9.7" — but the common error is reading 69.7 as centimeters, which would be 2'3", clearly impossible. The error runs the other direction too: seeing 177 on the metric chart and thinking 177 inches (which would be 14 feet, also impossible). Neither mistake survives contact with a reality check, but both appear in parenting forums with enough frequency that pediatricians keep a laminated conversion chart in the exam room.

The more consequential version of the unit error is in weight-for-height calculations. BMI uses kilograms and meters; a child recorded at 120 cm and 25 kg has a BMI of 17.4, which is healthy for a 7-year-old. If the height is misread as 120 inches (304.8 cm), the BMI drops to 2.7, which is impossible; if it is entered as 120 feet (3,657.6 cm), the software flags an error. These gross errors are caught automatically. The subtle error is entering 120 inches when the measurement was 120 cm — a plausible number (120 inches is 10 feet) that still produces an error flag, but only if the software has bounds checking. Some older clinic software does not. Checking that the unit toggle is set correctly before entering a measurement takes two seconds; finding and correcting a chart entry takes two appointments. If you need to convert a child's height from centimeters for a U.S. school health form that requests feet and inches, this page gives the correct feet-and-inches breakdown; for a form that requests only total inches, the /cm-to-inches page gives that figure directly.

Q: What is 178 cm in feet and inches? — 178 cm is 5 feet 10.08 inches, which rounds to 5'10". The decimal feet value is 5.8399. To verify: 5 × 30.48 = 152.4 cm, and 10 × 2.54 = 25.4 cm, totaling 177.8 cm — the 0.2 cm gap confirms the nearest-inch rounding. 178 cm in feet is the most common height-conversion search for men in metric-first countries comparing themselves to U.S. or UK benchmarks, and 5'10" is the honest unrounded answer.

Q: How many cm is 5 feet exactly, and why does the chart show 152.4? — One foot is exactly 30.48 cm by international definition (the international yard and pound agreement of 1959). Five feet is therefore 5 × 30.48 = 152.4 cm exactly, no rounding. The definition is exact — not an approximation — so 152.4 is not rounded. The figure appears in every reference table for the same reason: it is the algebraic product of the exact definition, not a measurement with uncertainty. If you are using a centimeters to feet chart and see a slightly different value for 5 feet, the chart is using a rounded conversion factor, typically 30.5 instead of 30.48, which introduces a 0.065% error — small for conversation, noticeable over longer distances or when chaining multiple conversions.

A lot of flat-pack furniture sold in East Asia is designed and dimensioned in millimeters, then labeled in centimeters on the product sheet. A dining table that is 75 cm tall and 120 cm wide is 750 mm x 1200 mm in the factory drawing. When that table arrives in a US house framed with 2x4 lumber and measured in 16ths of an inch, the carpenter fitting a custom bench around it needs to convert both ways in the same afternoon. 75 cm is 29.53 inches, which is 29 and 8.5/16 of an inch. No framing square has that mark; the carpenter rounds to 29½" (74.93 cm) and accepts a 0.6 mm gap. For a bench seat, that is fine. For a cabinet door that has to clear a 76.2 cm countertop by 3 mm, rounding to the nearest 8th of an inch introduces a 1.6 mm error that shows up every time the drawer opens.

The fractional-inch system used in US woodworking goes down to 1/16 inch, which is 1.5875 mm. A router template built to metric measurements produces cuts that land between 16th-inch marks, and the common fix is a reference card: 1 mm = 3/64", 2 mm = 5/64", 5 mm = 13/64", 10 mm = 25/64". In practice, cabinetmakers working from metric shop drawings hold 1 mm = 1/16" (a 0.4 mm overstatement) for rough work and 1 mm = 3/64" (accurate to 0.01 mm) for drawer-box tolerances. The difference shows up in a 600 mm panel: rounded at 1/16" it measures 23.625" (600.08 mm), off by 0.08 mm; rounded at 3/64" it measures 23.625" too — but only because 600 happens to land near a round 16th. Try 585 mm: that is 23.031", not 23" and not 23 1/16". The precise figure matters when the panel fits between two uprights whose spacing was cut from a framing diagram in inches.

The cleanest approach in a mixed-unit shop is to convert the entire cut list to one system before touching the saw. A Korean kitchen cabinet plan in mm converts to decimal inches (divide by 25.4), then each decimal inch converts to the nearest 1/32" for final cut marks. The /inches-to-cm page handles the reverse check: if the cut came out at 23¼" and the drawing called for 590 mm, typing 23.25 into inches gives 590.55 mm, a 0.55 mm surplus that fits inside cabinet-grade tolerances but would be tight in precision joinery. Writing the math out once and keeping the reference sheet taped inside the shop cabinet saves the mental conversion every time a piece goes to the saw.

In a typical US clinic visit, the nurse records height in inches on the paper chart — 67 inches for someone who is 5'7", which is 170.2 cm. The electronic health record converts that internally, usually by multiplying by 2.54, and the metric number is what feeds into BMI and body-surface-area calculations. For most patients the roundtrip introduces less than 0.5 cm of error, which shifts BMI by under 0.1 kg/m². But for someone measured in a country that records centimeters and then seen in the US, the problem runs the other direction: a Chinese health checkup form that lists 170 cm gets retyped by the American clinic as "67 inches" because 170 ÷ 2.54 = 66.93, rounded up. That 0.07-inch rounding shifts nothing meaningful. The real risk is a clerical mistake where the cm value is entered into the inches field directly, giving 170 inches — over 14 feet — which any reasonable system should reject, but not all older EMRs have height bounds checking.

The practical range for adults is roughly 150 cm (4'11", 59.1 inches) to 195 cm (6'4.8", 76.8 inches). A patient at 150 cm has a BMI denominator of 2.25 m²; at 195 cm it is 3.80 m². That spread means a 10 kg weight difference changes BMI by 4.4 points at 150 cm but only 2.6 points at 195 cm, so height accuracy matters more at shorter statures. Chinese national health screening standards require height to the nearest 0.1 cm; US physicals typically record to the nearest 0.5 inch. Converting a 0.5-inch measurement to centimeters gives a result accurate to about 1.3 cm — which is within acceptable error for adult BMI but meaningful for pediatric weight-for-height percentiles, where 1 cm shifts a 2-year-old by 3 to 4 percentile points near the median.

When a person's height is recorded in both systems across different documents, verifying consistency is straightforward: multiply feet by 30.48, add inches times 2.54, and compare to the cm value. A person recorded as 5'8" in the US and 172 cm in China has a discrepancy: 5'8" is 172.72 cm, not 172. That 0.72 cm gap is within rounding, but a record showing 5'8" in one system and 169 cm in another (5'6.5") flags a genuine error worth investigating before a dosing calculation runs on it. The /feet-to-cm page gives the exact cm value for any feet-and-inches input, which makes the cross-check a two-second task rather than a back-of-envelope one.

When someone buys clothes from an overseas retailer, the size recommendation usually runs through a lookup table that uses height in centimeters. A Japanese sportswear brand might say: height 165–170 cm, size M; 170–175 cm, size L. That 5 cm window is the boundary that determines fit across shoulders, sleeve length, and body length simultaneously. A shopper who is 168 cm but rounds to 170 when filling out the size quiz gets placed into L. The L garment assumes a torso 2–3 cm longer, which hangs noticeably below the waistband of medium-rise pants. The error started as a 2 cm overstatement, but because the sizing table uses hard cutoffs, it propagated into a full-size mismatch.

The same dynamic plays out with European sizing for dresses and coats. A German outerwear brand might list a size 38 for heights 168–172 cm and a size 40 for 172–176 cm. A shopper at 172 cm sits exactly on the boundary, and the brand expects the height measurement to come from a standing-against-the-wall measurement in centimeters, not a self-reported feet-and-inches figure that was converted. Self-reported heights in feet-and-inches run about 1 cm high on average — people round up, and the conversion from feet-and-inches to centimeters sometimes adds another rounding step. That means a person who says 5'8" (172.72 cm, often entered as 173) is at 172 cm on the boundary, and a sloppy conversion could place them at 174 or 175, pushing them into the larger size when the smaller would have fit.

Footwear sizing makes the effect worse because shoe length correlates to standing height through foot-length tables, and those tables are in centimeters in every European brand. A 179 cm man has an expected foot length of about 26.5–27 cm (EU 41–42, US 8–8.5). If his height is recorded as 181 cm because someone converted 5'11" as 181 (it is 180.3 cm) and the size chart uses 180+ to recommend EU 42, he orders the larger shoe and it slips at the heel. Two centimeters of height rounding resolved in the wrong direction cost him a shoe size. Checking height conversion carefully before submitting any international size recommendation costs thirty seconds; returning an ill-fitting shoe from overseas takes two to three weeks and sometimes a customs fee.

When someone converts 170 cm to feet on a basic calculator, the output is 5.57743 feet. The rounding of that to 5.58 is mathematically reasonable. The problem is that every visa form, driver's license application, and school enrollment sheet that asks for height in "feet" actually means feet and inches, with the feet and inches in separate boxes. Writing 5.58 in the feet box and nothing in the inches box tells the form that the applicant is five feet and fifty-eight hundredths of a foot tall, which is 5'6.96" — a legal height for most purposes but not what was intended, and not what matches a passport that says 170 cm. Some form-validation software treats 0.58 as the inches value and silently saves the height as 5'0.58", placing a 170 cm person at under 5'1" in the database. This is not hypothetical: it shows up in shipping manifests, sports registration databases, and school health records.

The correct procedure is always to convert 170 cm to 5 feet 6.93 inches, round the inches to the nearest whole inch (7), and enter 5 in the feet box and 7 in the inches box. The feet-and-inches display on this page does that step automatically. For forms that want a written-out height like "5'7\"", the apostrophe is feet and the quotation mark is inches — not the other way around. A US driver's license, for example, records height as 5-07, meaning 5 feet 7 inches, with a hyphen between feet and inches and a leading zero on single-digit inches. A school sports clearance form in California uses the same format. Writing 5.7 on either form is a different number (5 feet 8.4 inches by the decimal-feet rule) and will not match a passport that says 5'7".

Visa forms for countries that use metric ask for centimeters, and that direction is simpler: write 170, not 5.58, not 5'7". The common mistake on metric-country forms is entering the feet-and-inches value into the centimeter field, giving 507 cm (from "5-07") or 57 cm (from misreading the combined digit). Some applicants have had visa applications queried because their declared height of 57 cm placed them at a height consistent with a toddler. The fix at the source is to use this page for the feet-to-centimeters conversion when the target form wants metric, or the /feet-to-cm page for the reverse. Both pages show the result in the format the form is asking for, not the intermediate decimal that looks like a valid answer but is not the one any form was designed to receive.

A complete reference table from 150 cm to 200 cm in 1 cm steps shows a pattern that surprises most people: the fractional inches never land on a clean quarter. 150 cm converts to 4'11.055", so rounding to the nearest inch gives 4'11". 160 cm gives 5'2.992", which rounds to 5'3". 170 cm gives 5'6.929", rounding to 5'7". 180 cm gives 5'10.866", rounding to 5'11". 190 cm gives 6'2.803", rounding to 6'3". 200 cm gives 6'6.740", rounding to 6'7". Every one of those rounded answers is one inch higher than the centimeter value suggests at a glance, because all values in this range carry a fractional inch above 0.5. A person who self-reports as 5'11" is therefore approximately 180 cm, not 179 cm, and a person who says 6'3" is closer to 190 cm than to 191 cm.

The rounding direction matters in contexts where a one-centimeter error crosses a threshold. Pediatric growth charts set alarm intervals at specific centimeter values; a height recorded as 170 cm rounded from 5'7" is 170.18 cm, which stays in the same band. But a height recorded as 179 cm rounded from 5'10" is actually 5'10.866" = 179.07 cm, within 0.07 cm of the chart band boundary at 179 cm. Hospitals that accept patient-reported heights in feet and inches and convert them to centimeters for the electronic record should always store the unrounded decimal, not the whole centimeter, so downstream calculations — BMI, medication dosing by body surface area — preserve accuracy. The whole-centimeter display is cosmetic; the stored value should carry at least two decimal places.

For everyday use the safe rule is: when converting feet-and-inches to centimeters, multiply total inches by 2.54 and do not round until you have the final number. 5'11" = 71 inches × 2.54 = 180.34 cm, not 180 cm. 6'0" = 72 inches × 2.54 = 182.88 cm, not 183 cm. The two-centimeter spread inside a single inch means rounding at the wrong step accumulates errors that look small on a chart but matter in sports eligibility (height gates are often set at exact centimeter values), clothing cut, and medical forms. The converter on this page stores four decimal places internally and rounds only for display, which is why the feet-and-inches output and the centimeter output always convert back to each other without a discrepancy.

Furniture sold in North America is labeled in feet and sometimes fractional feet. A curtain panel listed as 7 ft long is 213.36 cm. A curtain panel listed as 7.5 ft is 228.6 cm. The 15-cm difference is enough to decide whether the panel puddles on the floor or floats above the baseboard. The problem appears when a customer in a metric country reads "7 ft" and searches for a panel that is "210 cm" — a reasonable mental conversion — and buys a panel that is actually 10 cm shorter than the window height requires. The 0.94 cm-per-foot rounding that seemed acceptable for a height measurement becomes a 6.6 cm shortfall on a 7-foot curtain, and 13.2 cm short on a 14-foot pair.

Bed frame labels compound this. A queen bed is standardized at 60 inches wide and 80 inches long in the US: exactly 152.4 × 203.2 cm. European queen (which is not a standard term; the equivalent is 160 × 200 cm) is 2.6 cm shorter and 7.6 cm wider. A customer who reads "queen" on a North American retailer's site and converts 80" to 200 cm has introduced a 3.2 cm error in the length dimension. For a platform bed with a built-in headboard alcove, 3.2 cm is the difference between the mattress sitting flush and the mattress being blocked from sliding fully into position. Flat-pack assembly instructions from North American brands sometimes list internal dimensions in inches with a centimeter conversion in parentheses, and that conversion is occasionally rounded to the nearest centimeter, which shifts the drill-hole position by up to 0.5 cm relative to the metric version of the same product sold in Europe.

The reliable method is to convert every dimension individually using exact multiplication (inches × 2.54) rather than rounding a total length, and to check whether the product label refers to outside, inside, or mattress-area dimensions. A bed frame listed as 82" long may have an inside mattress area of 80", with the 2" remainder split between headboard and footboard brackets. Converting 82" to cm (208.28 cm) and comparing against a 200 cm mattress looks safe, but 80" inside is 203.2 cm, leaving only 3.2 cm of clearance on each end once the mattress is in position. Curtain, bed, sofa, and shelving measurements in North American catalogs follow this inside-versus-outside ambiguity frequently; the centimeter conversion on this page converts exact values, but interpreting which dimension is being stated requires reading the product specification rather than the headline number.

Building codes and architectural drawings in metric countries specify clear floor-to-ceiling heights in meters, typically 2.40 m, 2.50 m, 2.60 m, or 2.70 m for residential construction. North American residential drawings use feet and inches, with common finished ceiling heights of 8'0", 9'0", 10'0", and 8'6". The apparent equivalences break down quickly: 8'0" = 243.84 cm, which is 3.84 cm taller than a 2.40 m room; 9'0" = 274.32 cm, which is 24.32 cm taller than a 2.50 m room. A contractor who reads a European drawing specifying 2.50 m clear height and frames the wall at 8'2" (the nearest "round" imperial measurement, = 248.92 cm) has built a ceiling that is 1.08 cm shorter than the drawing requires. In most jurisdictions that shortfall is within construction tolerance, but in a room with dropped ceilings or mechanical systems running in the plenum, it propagates into duct clearance calculations where every centimeter is load-bearing on the design.

The conversion chain in architectural work runs: structural slab-to-slab height minus ceiling tile plus raised floor equals clear height. Each step is stated in the drawing's native unit, and converting intermediate values introduces rounding. A metric drawing might show: slab-to-slab 3050 mm, ceiling tile 100 mm, raised floor 150 mm, clear height 2800 mm. An imperial contractor converts 2800 mm to 9'2.2" and frames at 9'2", losing 0.2" = 5 mm of clear height. Over a room with mechanical equipment requiring exactly 2800 mm clear, the 5 mm shortfall requires equipment repositioning. The professional standard is to work in the drawing's native unit throughout and convert only the final dimension for communication, never for intermediate calculation.

Room net height regulations in most European countries set 2.20 m as the minimum habitable height for a room to count toward the legal floor area. At 2.20 m exactly (= 7'2.6"), a contractor rounding to 7'2" (= 218.44 cm) has built a room that fails the 2.20 m threshold by 1.56 cm. The legal consequence is that the room may not be counted in the property's stated area, reducing the declared size of the apartment and potentially triggering a contract dispute. The same principle applies to stairwell clear heights: European codes commonly require 2.00 m minimum (= 6'6.74"), and a staircase framed at 6'6" (= 198.12 cm) is 1.88 cm under code. These are not hypothetical precision arguments; planning permission challenges citing unit conversion errors in submitted drawings appear in building control records in the UK, Germany, and the Netherlands. The converter on this page returns the exact centimeter value to two decimal places, which is the precision level needed for drawing submission and code compliance checking.
