Volume measures how much space a substance occupies. The most common everyday volume units are the US cup (236.59 mL), the metric cup (250 mL), and the milliliter (mL). Converting between these units is essential in cooking, baking, nutrition labelling, and recipe adaptation across different countries.
The US cup and the milliliter differ because the United States uses the customary measurement system while most of the world uses the metric system. A US recipe calling for 2 cups of milk means 473 mL — and an Australian or Canadian cook following that recipe would need to know this to measure accurately using their metric measuring jugs.
Our volume converters use internationally accepted values: 1 US cup = 236.5882365 mL exactly (by definition). All calculations are performed with full precision before rounding for display.
