Milliliters to US Cups Converter (mL to cups)
1 mL = 0.00422675 US cups; 250 mL is about 1.06 cups. Convert milliliters from metric recipes and cans to US cups, with a cups to mL chart.
US Cup (cup) = Milliliter (mL) × 0.00422675283773
Milliliter (mL): A milliliter is one thousandth of a liter and exactly the same volume as one cubic centimeter. There are 1,000 microliters in a milliliter and 1,000 milliliters in a liter.
US Cup (cup): The US customary cup is half a US pint: 8 US fluid ounces or 236.5882365 mL. US recipes use it; nutrition labels instead use a rounded 240 mL "legal cup".
| Milliliter (mL) | US Cup (cup) |
|---|---|
| 1 | 0.00422675283773 |
| 5 | 0.0211337641887 |
| 10 | 0.0422675283773 |
| 25 | 0.105668820943 |
| 50 | 0.211337641887 |
| 100 | 0.422675283773 |
Recipes from Europe, Asia and Australia give liquids in milliliters, and imported cans and cartons print only a metric volume, yet an American kitchen drawer is full of cup measures. Dividing milliliters by 236.5882365, the exact size of a US customary cup, gives the number of cups; the first chart covers amounts from a tablespoon-sized 15 mL up to a full liter.
Not every recipe that says "1 cup" means a US cup. Australian, New Zealand and Canadian recipes use a 250 mL metric cup, and Japanese recipes a 200 mL cup, so when a metric recipe gives both, follow the milliliters. The 250 mL row of the chart shows how far a metric cup is from a US one.

Formula
US Cup (cup) = Milliliter (mL) × 0.00422675283773
Milliliter (mL) = US Cup (cup) × 236.5882365
Both factors come from exact definitions: 1 us cup = 236.5882365 milliliters and 1 milliliter = 0.00422675283773 US cups (shown to 12 significant digits).
Example
Two conversions worked with the same factors the converter uses:
180 mL × 0.00422675283773 ≈ 0.760816 cup
1.25 cup × 236.5882365 ≈ 295.735 mL

Quick mental estimate
Divide the milliliters by 240, the label cup: 600 mL → 2.5 cups. The exact answer is 2.54 cups, so this shortcut lands about 1.4% low.

Frequently asked questions
How many US cups is 250 mL?
About 1.06 US cups, slightly more than one. In a recipe from Australia, New Zealand or Canada, 250 mL is exactly one metric cup, so an American cook can fill a US cup and add just under a tablespoon.
Can I use US cups for a recipe written in metric cups?
For soups, stews and most savory cooking, yes: a US cup is about 5% smaller than a 250 mL cup, and using the same cup for every ingredient keeps the proportions right. For baking, convert each amount from milliliters, or weigh the dry ingredients.
How many cups is a 400 mL can of coconut milk?
About 1.7 US cups. Many US brands sell coconut milk in 13.5 fl oz cans, about 399 mL, so a recipe written for either can size works with the other.
How precise is the result?
The converter uses the exact definitions above with browser floating-point arithmetic and shows up to 12 significant digits. The charts round to four decimal places for reading.
