Volumeexact by definition
The US customary cup is exactly 8 US fluid ounces, 236.5882365 millilitres, half a US pint. It is the base volume of American recipe writing, with the tablespoon and teaspoon as its subdivisions.
Watch out: The FDA's "legal cup" used on nutrition labels is exactly 240 mL, about 1.4% larger, and the metric cup of Australia, New Zealand and Canada is 250 mL, about 5.7% larger. A recipe that says "cup" without saying which is ambiguous by up to a tablespoon.
