This cups to ml converter turns US cups into milliliters as you type, so an American recipe works with a metric measuring jug. Baking is where it matters most: a recipe written in cups, read in a kitchen with ml markings, is easy to get slightly wrong by eye. It runs in your browser and spends no credits.
How many ml are in a cup
One US customary cup is exactly 236.5882365 milliliters, about 236.59 ml. It is half a US pint, or 8 US fluid ounces, and it equals 16 tablespoons or 48 teaspoons. That is the cup this converter uses.
Which cup is your recipe using
Not every cup is the same size, which is why conversions found online disagree:
- US customary cup: 236.59 ml. Most American cookbooks and measuring cups.
- US legal cup: 240 ml, used for serving sizes on US nutrition labels. It is 3.41 ml larger.
- Metric cup: 250 ml, used in Australia and New Zealand, 13.41 ml larger than the US cup.
- Imperial cup: 284.13 ml, half a UK pint, found in older British recipes.
For one cup the gap between 236.59 and 250 ml is small. Across four cups of liquid it reaches about 54 ml, enough to change a batter.
Cups to ml formula
Multiply the cups by 236.5882365:

Worked example: milk for pancakes
A recipe asks for 1 1/2 cups of milk. Type 1.5 and get 1.5 × 236.5882365 = 354.88 ml, so fill a metric jug to just under 355 ml. For 2/3 cup of oil, type 0.6667 for 157.73 ml. Small amounts are easier with spoons: a tablespoon is 14.79 ml and a teaspoon 4.93 ml, both in the unit list.
Cups measure volume. Flour or sugar measured in cups converts to milliliters here, not to grams, since a cup of flour and a cup of sugar weigh different amounts.
