The mL to cups factor
One US customary cup equals 236.588 milliliters, so to convert milliliters to cups you divide by 236.588. For example, 500 mL ÷ 236.588 = 2.11 cups. Note this is the US cup; a metric cup is 250 mL. Need the reverse? Use the cups to mL calculator.
Many people follow this up with the mL to grams calculator.
How to use this calculator
Enter a volume in milliliters and the converter instantly shows the equivalent in US cups, rounded to two decimals — handy for converting metric recipes to US cup measures. Just divide mL by 236.588.
Smaller units follow the same chain: 1 US cup is 8 US fluid ounces, 16 tablespoons or 48 teaspoons, so 1 fl oz is 29.5735 mL and 1 tablespoon is 14.79 mL. If a recipe asks for a third of a cup, that is about 78.9 mL.
Handy anchors: a 330 mL can is 1.39 cups, a 750 mL wine bottle is 3.17 cups, and a 1 litre carton is 4.23 cups. Two decimal places is more precision than most kitchen jugs can show, so round to the nearest quarter cup when you are pouring rather than weighing.
The mL to oz calculator is the natural next step once you have this figure.

Common conversions:
| Milliliters | US cups |
|---|---|
| 100 mL | 0.42 cups |

Watch which cup a recipe means. The US customary cup is 236.588 mL, the metric cup used in Australia and New Zealand is 250 mL, and US nutrition labels use a rounded 240 mL cup. A 250 mL metric cup is 1.06 US cups, so over four cups the difference is more than half a US cup — enough to change a batter. British recipes usually give millilitres or grams and avoid cups altogether.

- Does this use the US or metric cup?
- It uses the US customary cup (236.588 mL), not the 250 mL metric cup.
- Can I use this for dry ingredients like flour?
- Only if you know the volume, because a cup of flour and a cup of water weigh very different amounts. Millilitres and cups are both volume units, so the conversion is exact for liquids; for flour or sugar given in grams, use a grams-to-cups conversion with the right density instead.
