Work out litre to gallon instantly with clear inputs, formula shown and shareable results.
Converting Litres to US gallons is a single multiplication: one L equals 0.26417205 US gal, so the amount is multiplied by that factor. Switching the direction divides by the same factor instead. This factor is an exact definition, not a rounded approximation, so the conversion is precise at any scale. This uses the US liquid gallon (3.785411784 L). The Imperial gallon is 4.54609 L — about 20% larger — so fuel-economy figures are not interchangeable between the US and UK.
Litres → US gallons
US gal = L × 0.26417205
US gallons → Litres
L = US gal ÷ 0.26417205
One L is 0.26417205 US gal. That figure is exact by definition.
Divide by 0.26417205 instead of multiplying — or just switch the direction selector, which does it for you.
