About Miles per UK (Imperial) Gallon (MPG (UK))
Miles per UK (Imperial) Gallon is the figure used in the UK and Ireland, based on the larger 4.546-liter imperial gallon — the same car reports a higher MPG number in the US than in the UK purely because the gallons differ in size.
About Liters per 100 Kilometers (L/100km)
Liters per 100 Kilometers is the standard fuel economy figure across the EU and most of the world — unlike the other three units here, a LOWER number means better efficiency, since it measures fuel consumed per fixed distance rather than distance per fixed fuel.
