Fluid ounces to milliliters is needed to convert American drink sizes, cocktail recipes and cosmetic labels for metric readers. Nurses converting oral medicine doses and parents measuring formula also use it.
Coffee chains use ounce sizes. A Starbucks tall is 12 fl oz (354.9 ml), grande is 16 fl oz (473.2 ml) and venti hot is 20 fl oz (591.5 ml). Outside the US, many menus list the same drinks in milliliters, rounded to 350, 470 and 590 ml.
Medicine dosing is another case. Older US labels sometimes give doses in fluid ounces, while pharmacists and syringes use milliliters. One fluid ounce is 29.57 ml, so half an ounce is 14.8 ml, close to one tablespoon. When in doubt, use the milliliter scale on the dosing cup.
Bottled drinks in the US come in 8, 12, 16.9 and 20 fl oz sizes. The 16.9 fl oz bottle is exactly 500 ml, which is why that odd number appears on water bottles.
