How to convert miles per gallon to liters per 100 kilometers
Formula: L/100 km = 235.215 ÷ mpg
Worked example: 30 mpg → 235.215 ÷ 30 = 7.84049 L/100 km
Divide 235.215 by the mpg value. Because the relationship is inverse, the gaps are uneven: 20 mpg is 11.8 L/100 km, 30 mpg is 7.8 and 40 mpg is 5.9. A US pickup rated 18 mpg uses about 13.1 L/100 km.

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.
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.
