How litres convert to gallons
This page converts to US gallons. A US gallon is exactly 3.785411784 litres, so US gallons = litres ÷ 3.785, or litres × 0.264172.
In your head: divide by 4 and add 5%. For 20 litres, a quarter is 5, plus a bit, gives 5.25; the exact answer is 5.28 gallons.
US gallons and UK gallons are different
The UK imperial gallon is 4.54609 litres, about 20% bigger than the US one. The same amount of liquid is therefore fewer imperial gallons: imperial gallons = litres ÷ 4.546.
| Litres | US gallons | Imperial gallons |
|---|---|---|
| 1 | 0.26 | 0.22 |
| 5 | 1.32 | 1.10 |
| 20 | 5.28 | 4.40 |
| 45 | 11.89 | 9.90 |

Before converting, check where the figure came from. An American recipe, fuel price or aquarium size means US gallons. A British source, and older figures from Commonwealth countries, mean imperial gallons.
Fuel
A typical hatchback tank of 45 litres holds 11.9 US gallons. Fuel prices convert the other way round, because they are per unit: a price per litre multiplied by 3.785 is the price per US gallon. Fuel economy in miles per gallon also depends on which gallon is meant, which is why a British mpg figure for a car is higher than the American figure for the same car.
Smaller US measures
A US gallon divides into 4 quarts, 8 pints, 16 cups or 128 fluid ounces. So a litre is a little more than a US quart (1.057 quarts), which is a useful anchor: a one-litre bottle and a quart carton are nearly the same size.
Water and tanks
A litre of water weighs one kilogram, so a US gallon of water weighs about 3.79 kg, or 8.34 lb. A 1,000-litre overhead tank holds 264 US gallons. Aquarium equipment is often rated in US gallons: a 100-litre tank is about 26 gallons.
