Work out kilometres per litre converter instantly with clear inputs, formula shown and shareable results.
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.
L/100 km
L/100 km = 100 ÷ (km/L)
Miles per litre
mi/L = (km/L) ÷ 1.609344
mpg (US)
mpg = (km/L) × 3.785411784 ÷ 1.609344
15 km/L is 6.67 L/100 km, or about 35 mpg on the US scale — respectable for a petrol car.
They are the same thing. 'kmpl' is just an abbreviation of kilometres per litre used widely in India.
