How to convert liters per 100 kilometers to miles per gallon
Formula: mpg = 235.215 ÷ L/100 km
Worked example: 6 L/100 km → 235.215 ÷ 6 = 39.2024 mpg
Divide 235.215 by the L/100 km figure. A European compact at 5 L/100 km achieves about 47 US mpg, and a hybrid at 4 L/100 km about 59 mpg. Note that European test cycles (WLTP) and EPA ratings are measured differently.

What is a liter per 100 kilometers?
Liters per 100 kilometers measure how much fuel a vehicle burns over a fixed distance. Europe, Canada and Australia use it on window stickers. Lower is better, and fuel cost scales directly with it: a car at 5 L/100 km burns half as much as one at 10.
What is a mile per gallon?
Miles per US gallon are the fuel economy unit of US window stickers and EPA ratings. Higher is better. Because it is a distance per volume, savings are not linear: going from 10 to 20 mpg saves far more fuel than going from 30 to 40 mpg.
