How to convert uk miles per gallon to litres per 100 km
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 UK mpg corresponds to 282.480936332 L/100 km. Zero mpg or km/L cannot be converted to finite L/100 km; zero L/100 km corresponds to infinite mpg or km/L.
