The liters people look up most

1 L = 0.2642 gal: Careful with the gallon - an imperial one is 4.546 L, so the same litres give only 0.22 imperial gallons.
5 L = 1.3209 gal: A common bottled-water and paint-tin size across Europe, where the gallon figure is never printed.
10 L = 2.6417 gal: A large watering can, or a small portable fuel container.
20 L = 5.2834 gal: A jerry can, and 4.4 imperial gallons - the two gallons differ by a fifth, which is enough to matter when refuelling.
50 L = 13.2086 gal: A typical car fuel tank, and the number behind most European range and economy figures.
200 L = 52.8344 gal: The metric drum, against the American 55-gallon one. They are different drums, not two names for the same thing.

How the liters to gallons calculation works

A US gallon is exactly 3.785411784 liters:

US gallons = liters ÷ 3.785411784

Check which gallon you mean before using this. The imperial gallon still used in the UK for some purposes is 4.54609 liters — 20% larger. Converting 50 litres gives 13.21 US gallons but only 11.00 imperial gallons. That gap is big enough to misjudge a fuel tank, a chemical dilution or a shipping quote entirely.

This converter uses the US gallon, which is what American fuel pumps, milk jugs and recipes mean.

Everyday volumes:

A US car fuel tank, 50 L → 13.21 gal
A large SUV tank, 75 L → 19.81 gal
A UK jerry can, 20 L → 5.28 gal
A domestic water heater, 150 L → 39.63 gal

Fuel economy does not convert this way. Miles per gallon and litres per 100 km are reciprocal — one measures distance per volume and the other volume per distance — so you cannot convert the units and keep the number. 8 L/100 km is 29.4 US mpg, and the arithmetic is 235.215 ÷ (L/100 km), not a multiplication.

A US gallon of water weighs 8.34 lb; an imperial gallon weighs 10 lb, which is where the old British mnemonic "a pint's a pound and a quarter" comes from. The American version, "a pint's a pound the world around", works only for US pints.

For a rough figure, divide litres by 3.8.

Frequently asked questions

Why is a British mpg figure higher than an American one for the same car?

Because British fuel economy is quoted in miles per imperial gallon even though the fuel itself is sold in litres. An imperial gallon is 4.546 L against the US gallon’s 3.785 L, so the same car scores about 20% better on the UK figure: 40 US mpg is 48 UK mpg. Comparing a British road test with an American one without correcting for that flatters the car considerably.

Is a litre exactly a cubic decimetre?

It is now. Between 1901 and 1964 a litre was defined as the volume of one kilogram of pure water at maximum density, which made it 1.000028 cubic decimetres - 28 parts per million out. The definition was reverted in 1964, so a litre is exactly 1 dm³ and the old figure survives only in very precise measurements published before then.

How do I turn a tank size in litres into a driving range?

You need the consumption as well as the capacity, and the two are usually quoted in different systems. A 50 L tank is 13.21 US gallons, which at 32 US mpg gives 423 miles. The same 50 L at a European 7 L/100 km gives 714 km, or 444 miles. The gap between those answers is the test cycle rather than the arithmetic - WLTP and EPA figures are not comparable.
