How the Volume Converter works

Volumes are converted through the litre. US and UK (imperial) measures differ, so they are listed separately: a US gallon is 3.785411784 L while an imperial gallon is 4.54609 L.

Cubic units use the cube of the linear factor, so one cubic metre is exactly 1,000 litres.

Formulas used

General
target = value × litres(from) ÷ litres(to)
