Volume Converter
Convert between litres, gallons, cubic feet and cubic metres.
About this calculator
Volume units are a frequent source of confusion because "gallon" and "cup" don't mean the same thing everywhere, a US recipe's gallon is smaller than a UK gallon, and fuel economy figures, tank capacities and shipping volumes are quoted in litres, cubic feet or cubic metres depending on the source. This calculator converts a value between litres, millilitres, cubic metres, cubic feet, US gallons, UK/imperial gallons, US cups and more, routing every conversion through a common base of litres so mismatched systems, like litres to US gallons versus litres to UK gallons, come out exact rather than blended together. It removes the guesswork of picking the right gallon or cup definition and the risk of applying the wrong regional conversion factor to a recipe, fuel tank, or container specification.
Worked example
1 litre to US gallons
Result: 0.264 gal
