Gallons to Liters Converter
Switch a tank size between US gallons, liters and imperial gallons.
Type in any box. 1 US gallon = 3.785 L, 1 imperial gallon = 4.546 L.
US and imperial gallons aren't the same
A UK imperial gallon is about 20% bigger than a US gallon, so the same tank reads as fewer imperial gallons. If you're comparing a British spec sheet with an American one, convert both to liters first. There's a table of common tank sizes too.
