How to Convert Liter/Kilometer to Kilometer/Gallon (US)

This conversion uses an offset formula, so it cannot be described by a single multiplication factor.

Formula: km/gal = L/km × 3.7854117891

Reverse: L/km = km/gal × 3.7854117891

Step-by-Step Example

Start with your value in Liter/Kilometer. For example: 5 L/km
Apply km/gal = L/km × 3.7854117891
The result is: 0.757082 km/gal

About Liter/Kilometer

The liter/kilometer (L/km) is a unit of fuel economy. The liter/kilometer scale is offset from the kilometre per litre scale, so converting it requires both a factor and an offset rather than a single multiplier. UnitConvertLab converts it against every other fuel economy unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.

Common uses: fuel economy calculations, engineering and science, education.

About Kilometer/Gallon (US)

The kilometer/gallon (us) (km/gal) is a unit of fuel economy. One kilometer/gallon (us) equals 0.264172052 kilometre per litres. UnitConvertLab converts it against every other fuel economy unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.

Common uses: fuel economy calculations, engineering and science, education.
