Definition The litre per 100 kilometres, symbol L/100 km, is a non-SI unit of fuel consumption, accepted for use with the SI.   A vehicle that consumes one litre of fuel to travel a distance of 100 kilometres has a fuel consumption of one litre per 100 kilometres.

The fuel economy of a vehicle relates distance travelled and the amount of fuel consumed.

For a vehicle travelling at an average speed of 100 km/h, the fuel consumption rate, in litres per hour, will be equal to the fuel comsumption in litres per 100 kilometres.
