About Kilometres Per Litre Converter Calculator

km/L is the fuel-economy unit used across much of Asia and Latin America. It is a distance-per-fuel measure, so it converts to L/100 km by reciprocal (100 ÷ km/L) and to mpg by additionally rescaling kilometres to miles and litres to gallons. All four figures below describe the same efficiency.

Formulas
