How it works

There are two gallons. The US gallon is exactly 3.785411784 L, so US gallons = litres ÷ 3.785411784 (× 0.264172). The imperial gallon used in the UK is exactly 4.54609 L, so imperial gallons = litres ÷ 4.54609 (× 0.219969). The converter starts with US gallons; switch the target unit to imperial gallon if that is what you need.

A 50 L fuel tank holds 13.21 US gallons or 11.00 imperial gallons. A 20 L water cooler bottle is 5.28 US gallons. Fuel prices per litre versus per gallon, aquarium volumes and paint coverage are the usual reasons to convert.

How to convert litres to gallons

Formula: US gal = L × 0.264172052358.

For US gallons, divide the litres by 3.785411784 (a US gallon is defined as 231 cubic inches). Worked example for a 60 L fuel tank: 60 ÷ 3.785411784 = 15.85 US gal.

For UK (imperial) gallons, divide by 4.54609 instead: the same 60 L tank holds 13.198 imperial gallons. The imperial gallon is about 20% larger, so always check which one a source means.
