The US fluid ounce (fl oz) is a customary unit of volume equal to 1/128 of a US gallon, or about 29.5735 mL. It is the standard unit for liquid serving sizes on US nutrition labels. The US fluid ounce is slightly larger than the UK fluid ounce (28.4131 mL) — confusingly, the opposite direction from the gallons.
The US legal cup, as used in nutrition labels, equals exactly 240 mL; the US customary cup, used in recipes, equals 236.5882365 mL (half a US liquid pint, or 8 US fluid ounces). Convertitive uses the customary value, which matches how most US cookbooks specify quantities. UK and Australian metric cups are 250 mL — yet another small but consequential difference.
