How to convert liters per 100 kilometers to miles per imperial gallon
Formula: mpg (UK) = 282.481 ÷ L/100 km
Worked example: 6 L/100 km → 282.481 ÷ 6 = 47.0802 mpg (UK)
For imperial gallons, divide 282.481 by the mpg value. A UK rating of 50 mpg equals 5.65 L/100 km.

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 imperial gallon?
UK mpg use the imperial gallon of 4.546 liters, 20% larger than the US gallon. The same car therefore shows a higher figure in Britain: 40 UK mpg is only about 33 US mpg.
