Fuel economy converter
The only category on this site where the conversion is a reciprocal, not a multiplication: more L/100 km means worse economy. Because the reciprocal of a fraction is still a fraction, these conversions stay exact.

About fuel economy units
Convert mpg (US and imperial), L/100 km and km/L.
The only category on this site where the conversion is a reciprocal, not a multiplication: more L/100 km means worse economy. Because the reciprocal of a fraction is still a fraction, these conversions stay exact.
Dimensional formula: L⁻². Every conversion on this page goes through the kilometer per liter, using exact fractions rather than decimal approximations. Read how that works →
