Quick answer: Divide milliliters by 236.588 to get US cups. 1 US cup = 236.588 mL. So 100 mL ≈ 0.42 cups, 250 mL = 1.057 cups, and 500 mL ≈ 2.11 cups.
Milliliter to Cup (US)
Instantly convert milliliter to cup (us) with fast, accurate, real-time results.
Most metric recipes list liquids in milliliters, but American measuring cups don't have mL markings on the front. This page gives you the conversion formula, a table of common recipe amounts, and a guide to reading the mL scale that's already printed on the back of most US measuring cups. For the reverse, see the cups to mL converter.
Formula: mL to Cups
The US customary cup is defined as exactly 8 US fluid ounces, which equals 236.5882365 mL. To convert:
Or flip it: multiply cups by 236.588 to get mL. A quick mental shortcut — divide by 240 — gives you a result within 1.4% for everyday cooking, which is close enough for most liquids.

Reading Measuring Cup Markings
Most American liquid measuring cups (Pyrex, OXO, Anchor Hocking) have a secondary mL scale printed on the opposite side or in a lighter color. Here's how those markings map to the cup fractions:
| Cup mark | mL mark on cup | Exact mL |
|---|---|---|
| ¼ cup | 60 mL | 59.15 mL |
| ⅓ cup | 75 mL | 78.86 mL |
| ½ cup | 125 mL | 118.29 mL |
| ⅔ cup | 150 mL | 157.73 mL |
| ¾ cup | 175 mL | 177.44 mL |
| 1 cup | 250 mL | 236.59 mL |
| 2 cups | 500 mL | 473.18 mL |
Baking Conversions from Metric Recipes
European and Australian baking recipes list everything in mL or grams. The most common liquid amounts and their cup equivalents:
Milk, water, and thin liquids
| Recipe calls for | Use this many cups | Notes |
|---|---|---|
| 50 mL | 3½ tbsp | Too small for a cup measure — use tablespoons |
| 100 mL | ⅓ cup + 1½ tsp | Closest: just under ½ cup |
| 120 mL | ½ cup | Exact ½ cup = 118.3 mL; 120 mL rounds fine |
| 150 mL | ⅔ cup | Rounds within 5 mL of ⅔ cup mark |
| 200 mL | ¾ cup + 1 tbsp | Use ¾ cup for most recipes |
| 250 mL | 1 cup + 1 tsp | Essentially 1 cup — within 1% |
| 300 mL | 1¼ cups | 1¼ cups = 296 mL; rounds well |
| 400 mL | 1⅔ cups | Or ¾ cup + ¾ cup |
| 500 mL | 2 cups + 1 tsp | Essentially 2 cups (1 pint) |
| 600 mL | 2½ cups | 2½ cups = 591 mL; rounds well |
| 750 mL | 3 cups + 1½ tbsp | Use 3 cups for general cooking |
| 1,000 mL | 4¼ cups | 4 cups + ¼ cup; or use a liter measure |
Oil, buttermilk, and thick liquids
The mL-to-cup math is the same for all liquids — density doesn't change the volume conversion. However, thick liquids like honey, molasses, or sour cream are often easier to measure by weight. If your recipe gives both grams and mL for a thick ingredient, the gram weight is more accurate. For small amounts of oil or vanilla extract, the tablespoons to teaspoons converter is more useful than cups.

| 1 mL | 0.0042 | 50 mL | 0.211 | 300 mL | 1.268 |

Other Cup Sizes
Not all cups are the same size. If a recipe uses a non-US cup, the conversion is different:
| Cup type | Volume | 100 mL in these cups |
|---|---|---|
| US customary cup | 236.588 mL | 0.423 cups |
| US legal cup (FDA) | 240 mL | 0.417 cups |
| Metric cup (AU, CA, NZ) | 250 mL | 0.400 cups |
| Imperial cup (UK, old) | 284.131 mL | 0.352 cups |
| Japanese cup (合, gō) | 200 mL | 0.500 cups |
Australian and Canadian recipes use the 250 mL metric cup, so "1 cup" in those recipes equals about 1.057 US cups. The difference is small for most dishes but adds up in large-batch baking. For mL ↔ larger volume units, see the liters to gallons converter or the fluid ounces to mL converter.
FAQs About mL to Cups
How many mL is 1 cup?
One US customary cup is exactly 236.588 mL. The FDA's "legal cup" (used on Nutrition Facts labels) rounds this to 240 mL. For everyday cooking, both values work fine.
Is 250 mL equal to 1 cup?
Not exactly. 250 mL equals about 1.057 US cups — roughly 1 cup plus 1 teaspoon. However, 250 mL is exactly 1 metric cup (used in Australia, Canada, and New Zealand), so this confusion often comes from reading metric recipes.
How do I convert mL to cups without a calculator?
Divide by 240 for a quick estimate — it's within 1.4% of the exact answer. For example, 480 mL ÷ 240 = 2 cups (exact is 2.029 cups). Good enough for soups, sauces, and most baking.
How many mL is ¼ cup?
¼ cup is 59.15 mL — your measuring cup's "60 mL" mark. Similarly, ½ cup = 118.3 mL and ¾ cup = 177.4 mL.
100 mL is how many cups?
100 mL ÷ 236.588 = 0.4227 cups, which is just under ½ cup (about ⅓ cup + 2½ tablespoons). For a quick kitchen estimate, use just under ½ cup.
Does 1 mL of water equal 1 gram?
Yes, at standard temperature and pressure 1 mL of pure water weighs exactly 1 gram. This is by design — the original metric system defined the gram that way. For other liquids, density varies: 1 mL of whole milk ≈ 1.03 g; 1 mL of vegetable oil ≈ 0.91 g.
