How to convert cups to millilitres

Both units measure volume, so no ingredient is involved. The converter turns your input into a shared base unit (millilitres) and divides by the target unit's factor. One cup is 236.5882 millilitres; one millilitre is 1 millilitres.

The full factors are kept until the final display is rounded. Use the "more precision" line on the result card when you need more decimals, and remember that a rounded kitchen fraction is a convenience rather than an exact equivalent.

Choose the measurement your recipe means

The default cup is US customary at 236.5882365 ml. Metric and Australian cups use 250 ml. A metric tablespoon is 15 ml; an Australian tablespoon is 20 ml. Fluid ounces, pints, quarts and gallons in this interface stay US liquid units whichever cup system you select.

For dry ingredients, check whether the recipe asks for a packed, sifted, chopped or level measure. Use the same preparation as the reference, and prefer the recipe author's gram quantities when they are given.

A few useful answers

Kitchen questions, answered.

Do I need to choose an ingredient?

Not for this pair: both units measure the same dimension. You will need an ingredient if you switch between a weight unit and a volume unit.

Can I enter a fraction?

Yes. Enter a decimal such as 0.5, a fraction such as 1/2, a mixed fraction such as 1 1/2, or a Unicode fraction such as ½. Blank, negative and zero-denominator inputs are rejected with a message.

Why does switching the cup system change the result?

US customary cups hold 236.5882365 ml. Metric and Australian cups hold 250 ml. The same amount therefore occupies a different number of cups, and Australian tablespoons (20 ml) differ from metric ones (15 ml).
