How to Convert ml to Cups
To convert milliliters to cups, divide the number of milliliters by the milliliters in one cup for the cup standard you are using.
Cups = milliliters ÷ ml per cup
US customary cups = milliliters ÷ 236.588
For example, to convert 250 ml to US customary cups:
250 ÷ 236.588 = 1.0567 cups ≈ 1.06 cups
Therefore, 250 ml equals approximately 1.06 US customary cups. The same 250 ml equals exactly 1 metric cup.
How Many ml Is 1 Cup?
It depends on the cup standard, not on the ingredient, because both milliliters and cups measure volume. A US customary cup is 236.59 ml, a metric cup is 250 ml, a US legal cup is 240 ml, and an imperial cup is approximately 284.13 ml.

Why Cup Standards Give Different Results
Milliliters are a fixed metric volume measurement, but the size of a cup varies between measurement systems. This is why the same milliliter amount can equal a different number of US customary, US legal, metric, or imperial cups.
How to Measure ml and Cups Accurately
For liquid measurements, place the measuring cup on a level surface and read the measurement at eye level. When a recipe gives milliliters, using a measuring jug marked in milliliters can help avoid unnecessary conversions.
