How the Unit Converter works

One US cup is 236.5882365 milliliters. Both units are defined against the same SI base unit, so the factor is derived from two exact definitions rather than measured. It is exact in principle and does not land on a round number.

Worked through: 0.75 cup x 236.588236 = 177.441 ml.

Going the other way, one milliliter is 0.0042267528 US cups.

To convert without a calculator, multiply by 236.6. Rounding that to 240 is within 1.4% for most purposes.

A US cup is 236.6 ml. A metric cup is 250, an imperial cup 284, and a Japanese cup 200. Recipes rarely say which, and the 6% gap between US and metric is enough to matter in baking, where ratios are the whole thing.

Precision is worth matching to the input. A measurement given as 0.25 cup carries one or two significant figures, and reporting its conversion to six implies a precision the original never had.
