The US cups people look up most

0.25 cup = 59.15 mL: Four tablespoons, which metric recipes write as 60 ml and nobody measures more precisely than that.
0.5 cup = 118.29 mL: Eight tablespoons, and the halfway point most recipes simply round to 120 ml.
0.75 cup = 177.44 mL: Twelve tablespoons, rounded to 175 ml in most British recipes.
1 cup = 236.59 mL: A metric cup - UK, Australia, NZ, Canada - is 250 ml, which is 5.7% more than the American one this converts.
2 cup = 473.18 mL: Also a US pint - the imperial pint is 568 ml, a fifth larger again.

How the cups to ml calculation works

A US customary cup is 236.5882365 milliliters — 8 US fluid ounces:

milliliters = US cups × 236.588

"A cup" means at least four different things, and this is the single biggest source of failed recipes:

Cup	Milliliters	Used in
US customary	236.59	US recipes
US legal	240	US nutrition labels
Metric	250	UK, Australia, NZ, Canada
Japanese	200	Japanese recipes

An Australian cup is 5.7% larger than an American one. Across a cake recipe using four cups of flour, that is nearly a full extra US cup of flour, which is the difference between a sponge and a brick.

This converter uses the US customary cup, which is what an American recipe means unless it says otherwise.

Standard fractions:

¼ cup → 59.15 ml
⅓ cup → 78.86 ml
½ cup → 118.29 ml
¾ cup → 177.44 ml
1 cup → 236.59 ml
2 cups (a US pint) → 473.18 ml

Cups measure volume, not weight — and for dry goods that is the real problem. A cup of flour is 120–150 g depending on whether it was scooped or spooned and how settled the bag was. That is a 25% swing on the main structural ingredient. For bread and pastry, weigh in grams; cups are fine for liquids, where volume is exactly what you want.

Enter fractions as decimals above: 0.75 rather than "3/4".

Frequently asked questions

Why does my measuring jug disagree with my cup set?

Because jugs are usually metric and nested cup sets are usually American. A jug sold in Britain or Australia marks its cup line at 250 ml, while a US cup set holds 236.59 ml, so using the jug for an American recipe adds 5.7% to every liquid measure. If you own both, pick one and use it for the whole recipe rather than alternating.

How do I measure half of a third of a cup?

With spoons. A third of a cup is 78.86 ml, so half of it is 39.4 ml - near enough 2 tablespoons and 2 teaspoons, since a US tablespoon is 14.79 ml and a teaspoon 4.93 ml. Halving an awkward cup fraction by eye is where volume measuring falls apart: the spoon set beats a half-filled cup, and a scale beats both.

Does a cup of butter mean melted or solid?

Solid, packed into the cup. One US cup of butter is two sticks, 8 fl oz by the markings and 227 g on a scale. Packed solid butter and melted butter do not fill a measure the same way, so melting first and then measuring gives a different quantity. American wrappers are printed with tablespoon marks precisely so you can cut on the line and skip the cup.
