One litre is 0.264172 US gallons, because a US liquid gallon is defined as exactly 3.785411784 litres. The imperial gallon used in the UK is larger, at 4.54609 litres, so the same number of litres is only 0.219969 imperial gallons — about seventeen per cent fewer.
How to convert litres to gallons
1 Enter the volume in litres.
2 Read the answer in US gallons.
3 For imperial gallons, divide the litres by 4.54609 instead — the difference is large enough to matter.
Fuel economy is where the two gallons cause real trouble. Thirty miles per US gallon is 36 miles per imperial gallon, and 7.84 litres per 100 km. A car advertised at "40 mpg" in Britain is not the same car as one advertised at 40 mpg in the United States, and neither figure converts to the other by simple arithmetic.
