How the liters to gallons converter calculation works

A US gallon is exactly 3.785411784 liters:

US gallons = liters ÷ 3.785411784

Check which gallon you mean before using this. The imperial gallon still used in the UK for some purposes is 4.54609 liters — 20% larger. Converting 50 litres gives 13.21 US gallons but only 11.00 imperial gallons. That gap is big enough to misjudge a fuel tank, a chemical dilution or a shipping quote entirely.

This converter uses the US gallon, which is what American fuel pumps, milk jugs and recipes mean.

Everyday volumes:

  • A US car fuel tank, 50 L → 13.21 gal
  • A large SUV tank, 75 L → 19.81 gal
  • A UK jerry can, 20 L → 5.28 gal
  • A domestic water heater, 150 L → 39.63 gal

Fuel economy does not convert this way. Miles per gallon and litres per 100 km are reciprocal — one measures distance per volume and the other volume per distance — so you cannot convert the units and keep the number. 8 L/100 km is 29.4 US mpg, and the arithmetic is 235.215 ÷ (L/100 km), not a multiplication.

A US gallon of water weighs 8.34 lb; an imperial gallon weighs 10 lb, which is where the old British mnemonic "a pint's a pound and a quarter" comes from. The American version, "a pint's a pound the world around", works only for US pints.

For a rough figure, divide litres by 3.8.
