Worked examples
A 50-litre car fuel tank
50 l ÷ 3.785411784 = 13.2086 gal (US)
50 litres = 13.2086 US gallons. About 13.2 US gallons, a typical tank for a small family car. In UK gallons it is about 11.
A 20-litre water jerrycan
20 l ÷ 3.785411784 = 5.2834 gal (US)
20 litres = 5.2834 US gallons. Just under 5.3 US gallons. Full of water it weighs about 20 kg, plus the can.
Converting litres to US gallons in real life
Fuel, water and paint are sold by the litre in most of the world and by the gallon in the US. Car fuel tanks, aquarium sizes, water heaters, rain barrels and garden sprayers all show up in both units, so comparing products often means converting.
The biggest mistake is mixing up US and UK gallons. A UK gallon holds about 20% more than a US gallon, so fuel-economy figures in UK miles per gallon look better than the same car in US mpg. If you see "gallons" on a British website, it almost always means the imperial gallon. For small volumes, ml to oz is easier.
