How to convert litres per 100 kilometres to kilometres per litre
Fuel economy is a reciprocal conversion, not a simple multiplication. UK and US gallons have different volumes, so their miles-per-gallon figures are not interchangeable.
For example, 1 L/100 km corresponds to 100 km/L. Zero mpg or km/L cannot be converted to finite L/100 km; zero L/100 km corresponds to infinite mpg or km/L.
