L to gal Converter

How L to gal works

Convert litres to US gallons instantly. 1 L = 0.2641721 gal, with a live result and a quick reference table. Everything happens inside this page: the tool reads your input, runs the calculation or conversion locally, and hands the result back to you. Nothing is transmitted, because there is no backend to transmit it to.

That design choice is deliberate. Most free tool sites upload your files to a server, process them there, and quietly keep a copy. Toolcin cannot do that — the site is a set of static files. If your connection dropped the moment the page finished loading, every tool would still work.

Litres and the US gallon

One US liquid gallon is exactly 3.785411784 litres, so litres to gallons multiplies by 0.2641720524. The definition is exact and has not changed since the gallon was tied to the litre.

A 5-litre bottle is 1.321 gallons. A 50-litre tank is 13.209 gallons. Fuel economy is where this pair causes the most confusion, because the US and the UK also use different gallons.

This is the US gallon, not the imperial one

The imperial gallon — still used for fuel in the UK, though litres are now standard at the pump — is 4.54609 litres, about 20% larger. Converting with 3.785 when the source meant imperial produces a figure that is roughly a fifth too small.

If a British source mentions mpg, it means miles per imperial gallon, and the number will look better than the same car measured in US mpg. That is the unit, not the car.

Fuel cost, not just volume

To price a fill, convert the volume and multiply by the price per gallon — or work entirely in litres, which is what most of the world does at the pump. The conversion only matters when the price is quoted in the other unit.

For mpg to l/100km you cannot use this factor alone: mpg is distance per volume, so the relationship is inversely proportional. That needs the fuel cost calculator, not a straight unit swap.
