Cups to Millilitres
1 cup = 240 millilitres
Converting cups to millilitres is the single most useful step when cooking a US recipe with metric measuring tools. This site uses the 240 ml metric cup that most modern US recipes and nutrition labels assume, so 1 cup = 240 ml, ½ cup = 120 ml and ¼ cup = 60 ml. Be aware the older US customary cup is 236.6 ml and a legal Australian cup is 250 ml, so a recipe's country of origin can shift the result by a spoonful.

How to convert cups to millilitres
To convert cups to millilitres, multiply by 240. This is a volume conversion, so it applies to any liquid or dry ingredient measured by volume, water, oil, milk, flour, and more.
Common conversions: 2 cups = 480 millilitres · 4 cups = 960 millilitres · 8 cups = 1,920 millilitres · 16 cups = 3,840 millilitres.
Tip: For water, milk and other thin liquids, millilitres and grams are interchangeable (1 ml ≈ 1 g), so a kitchen scale set to grams doubles as a millilitre measure.
For ingredient-specific weight conversions (like cups to grams of flour or rice), see our ingredient converters.
