Convert millilitres to cups and back — US customary, US legal, or metric cup. A pure volume conversion, independent of ingredient.
A cup is a unit of volume, so converting to millilitres doesn't depend on what's in it. The catch is which cup: a US customary cup is 240 ml, but a metric cup (used in the UK, Australia and much of the world) is 250 ml. Pick the right standard above.
| Unit | In millilitres |
|---|---|
| 1 cup (US) | 240 ml |
| 1 cup (metric) | 250 ml |
| 1 tablespoon | 14.79 ml |
| 1 teaspoon | 4.93 ml |
| 1 fluid ounce (US) | 29.57 ml |
