Volume Converter

Convert volume and capacity between litres, millilitres, cubic metres, US and UK gallons, cups, pints and more.

What is the Volume Converter?

Volume measures the space a liquid or object occupies. US and UK gallons differ, which matters when comparing fuel or recipes.

How does it work?

Every unit is defined by an exact factor relative to the litre. The value is converted to the litre and then to the target unit, so any pair of units can be converted consistently. Results are shown with up to 10 significant digits.

Formula

1 US gallon = 3.785 L
1 UK gallon = 4.546 L
1 m³ = 1,000 L

Example

10 litres = 2.64 US gallons = 2.2 UK gallons.

Frequently asked questions

Is a litre the same as a kilogram?
