About these units
MPG (UK)
Miles per gallon (UK) uses the larger imperial gallon, so UK figures are about 20% higher than US mpg for the same car.
L/100km
Liters per 100 km measures fuel used to travel 100 kilometers. Lower numbers mean better efficiency, the metric standard in Europe.
Conversion formula
Some fuel-economy units measure distance per volume (mpg, km/L) while L/100km measures volume per distance, so converting between those groups is a reciprocal relationship, not a constant multiplier.
