liters to gallons converter

How to convert liters to us gallons

This page converts to the US liquid gallon, which is exactly 231 cubic inches and therefore exactly 3.785411784 litres. Divide litres by 3.785411784. One litre is 0.2642 US gallons. The imperial gallon used in the UK is a different unit, exactly 4.54609 litres, so a litre is only 0.2200 imperial gallons. Using the imperial factor on a US jug understates the volume by about 17 percent. The unit converter lists both gallons. This page is the US one, and the pitfalls say so again because the search query 'gallons' does not.

Fuel in a metric country against a US tank rated in gallons, aquariums, and paint. A 50 litre tank is 13.209 US gallons. A US gallon of milk is 3.785 litres, so the other direction is the one you want when the jug is already in gallons.

Worked example: Liters to US gallons

One litre is 0.2642 gal of a US liquid gallon. The gallon on this page is exactly 3.785411784 litres, 231 cubic inches. An imperial gallon is 4.54609 litres, so the same litre is only about 0.220 imperial gallons. A 50 litre fuel can is 13.209 gal. Ten litres is 2.642 gal. Miles per gallon inherit this choice of gallon. A UK mpg is not a US mpg. A cubic metre is 1000 litres and has to be scaled before this division.

Pitfalls for liters to us gallons

• US gallon and imperial gallon are not interchangeable. Imperial is 4.54609 L. US is 3.785411784 L.
• The US dry gallon is another historic unit and is not this liquid gallon.
• Miles per gallon depends on which gallon. A UK mpg is not a US mpg even at the same fuel use.
• Cubic metres are 1000 litres. Do not divide a cubic metre by 3.785 and call it gallons without the 1000.
