About Litre To Gallon Calculator

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.
