Convert litres per 100 km to kilometres per litre and miles per gallon — US and UK figures shown separately, because their gallons give different answers.
5 litres/100 km is 20 kilometres/litre. US and UK MPG give different numbers because their gallons differ.
Consumption and economy are reciprocal: kilometres/litre = 100 ÷ litres/100 km. MPG uses the selected gallon definition.
Litres/100 km, Kilometres/litre, MPG (US), MPG (UK). Read the labels carefully: regional or decimal/binary variants are separate choices.
They measure opposite things: distance per unit of fuel versus fuel per unit of distance. As a car improves, MPG rises while consumption falls — the converter handles the inversion.
