Cups to ml and ml to Cups

US cups to millilitres formula

ml = cups × 236.5882365

1 US cup = 236.5882365 millilitres, so multiply US cups by 236.5882365. Going the other way, 1 millilitre = 0.0042267528 US cups.

How the Cups To Ml works

The cup is a volume, not a weight, and it is not the same size everywhere. An American recipe, an Australian one and a 1970s British cookbook can all say "1 cup" and mean three different amounts. For most cooking the gap is small enough not to matter, but in baking a 6% difference in liquid can change a cake's texture, so it pays to know which cup a recipe means.

Cups to ml: which cup?

• US customary cup: half a US pint, 8 US fluid ounces, exactly 236.5882365 ml. This is the cup in American recipes and on US measuring cup sets, and the one this converter uses.
• US legal cup: 240 ml, used on US nutrition facts labels for serving sizes.
• Metric cup: 250 ml, used in Australia, New Zealand, Canada and South Africa, and on most measuring jugs sold in the UK.
• UK imperial cup: 10 imperial fluid ounces, about 284 ml. It appears in older British recipes and is rarely used today.

The formula

ml = cups × 236.5882365, and cups = ml ÷ 236.5882365. For a metric cup, multiply by 250 instead. In practice, 1 US cup is 237 ml, and rounding to 240 ml is fine for anything but baking.

Worked examples

The first example is a US pancake recipe calling for 1½ cups of milk. 1.5 × 236.59 = 354.9 ml, so measure 355 ml. If you used a metric cup instead, you would pour 375 ml, 20 ml more.

The second example goes the other way. A 400 ml tin of coconut milk is 400 ÷ 236.59 = 1.69 US cups, so a recipe asking for 1¾ cups needs a splash more than one tin.

A third example: a third of a cup is 78.9 ml, which most people round to 80 ml.

How many ml in a cup, and in common fractions

There are 236.59 ml in a US cup and 250 ml in a metric cup. The table gives both for the fractions found on measuring cup sets, with US fluid ounces for reference.

How to read the result

• cup equals gives the volume in millilitres, to as many decimals as the factor carries. Round to the nearest 5 ml for a measuring jug.
• Conversion shows the factor, 1 cup = 236.5882365 ml. After a swap it reads 1 ml = 0.0042 cup.
• Inverse gives the factor for the opposite direction.

Tips and pitfalls

• Cups of flour are not millilitres of flour. A cup measures volume, and how much flour fits depends on how it is scooped. For dry ingredients, weigh them with the cups to grams converter.
• Check the recipe's origin. Australian and New Zealand recipes use 250 ml cups and 20 ml tablespoons. American recipes use 237 ml cups and 15 ml tablespoons.
• Read liquids at eye level. A measuring jug read from above can be off by 10 ml or more.
• Scale with one system. When halving or doubling, convert once and scale the millilitres with the recipe scaler rather than mixing cups and ml.
