When do you convert oz to ml?
Fluid-ounces-to-milliliters is essential when cooking from American recipes abroad or buying drinks in metric countries: the recipe's 8 fl oz of water is about 237 ml, and a '20 oz' coffee is 591 ml. Bartenders use it constantly — most cocktail recipes are built on 1 fl oz (30 ml) jiggers.
Bartending, coffee, and baby formula
Cocktail recipes are built on the ounce — a standard jigger is 1.5 fl oz (44 ml), and most classic recipes specify 0.5, 0.75, or 2 fl oz pours. Metric bartenders convert on the fly: a '2 oz rye' Manhattan becomes 59 ml, and since jiggers sold in Europe are marked in milliliters, the 30/60 ml cups cover the standard 1/2 oz and 2 oz pours with rounding that no palate can detect.
Baby formula is where this conversion stops being casual: mixing ratios are specified per fl oz of water in US instructions and per 100 ml elsewhere, and getting the ratio wrong affects nutrition density for infants. Follow the exact numbers — 1 US fl oz = 29.5735 ml — and use the calculator above rather than the 'about 30' shortcut. Coffee brewing sits in between: the SCA golden ratio (1 g coffee per 16-17 g water) is metric-native, and the '1 tablespoon per 6 oz cup' American rule is an approximation of the same thing.
