About the Volume Converter
The volume converter switches between millilitres, litres, US cups, pints, quarts and gallons. It converts through the litre using US customary definitions (1 US gallon = 3.785411784 L), which is what most American recipes and product labels use. Imperial (UK) gallons and pints are about 20% larger, so use the gallon calculator if you need UK units.

Worked example
