Formula
A US legal cup is one-sixteenth of a US liquid gallon:
milliliters = US cups × 236.5882365
The cups-to-grams page uses an ingredient weight, not this volume. A metric cup of 250 ml is a different cup.
Assumptions
- The cup is the US legal cup.
- The value can be zero and cannot be negative.
- The result is shown with up to six decimal places.
Worked example
1 US cup equals 236.588237 milliliters.
Input definitions
- US cups
- Legal cups of 236.5882365 milliliters.
Limitations
Many recipes treat a cup as 240 milliliters. That kitchen rounding is not applied here.
