About Liter/100km

The liter/100km (L/100km) is a unit of fuel economy. The liter/100km 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.
