Convert cups to milliliters (cup to mL)
To convert cups to milliliters, multiply the value in cups by 236.5882365. It turns American recipe measures into milliliters for a metric measuring jug or kitchen scale. This cups to ml converter works both ways: type cups or milliliters into either box above and the other box, the worked formula and the chart below update as you type.
The US customary cup is 8 US fluid ounces, or half a US pint — exactly 236.5882365 mL. It is the standard measuring cup in American recipes. US nutrition labels use a rounded 240 mL cup, while Australia, New Zealand and Canada use a 250 mL metric cup. One US cup is 236.588 milliliters.
The milliliter (mL), or millilitre, is one thousandth of a liter — exactly one cubic centimeter, which is why doctors and engineers also call it a cc. Going the other way, one milliliter equals 0.00422675 US cups. Milliliters are printed on drink cans and bottles, medicine syringes, cosmetics and metric recipes.
