What is a UK gallon?
The imperial gallon, defined as exactly 4.54609 litres (UK Weights and Measures Act 1985); about 20% larger than the US gallon. Used in the UK and Canada for fuel economy (miles per gallon), garden and aquarium volumes, and older fuel prices.
Litres to imperial gallons in the UK and Canada
UK and Canadian fuel is sold by the litre, but car fuel economy in the UK is still quoted in miles per imperial gallon, so drivers often need litres in imperial gallons. One imperial gallon is exactly 4.54609 litres, about 20% more than a US gallon.
- A 50 L tank = 11 imp gal
- A 60 L tank = 13.2 imp gal
- A 20 L jerry can = 4.399 imp gal
If a figure comes from a US source (a US car review or recipe), use the litres to US gallons page instead.
When You Need to Convert Liters to UK Gallons
Liters are used mainly in Canada, the UK and most of the world, and in US science, medicine and nutrition labels, while UK gallons are used mainly in the UK (pub pints, fuel economy in mpg) and older Canadian recipes. This conversion bridges the US customary and metric systems, so it comes up whenever a figure crosses the US border with Canada or the Atlantic with the UK: product specifications, travel, recipes, school work and trade.
