UnitSnapMiles per US Gallon to Liters per 100 km
1 mpg = 235.2146 L/100 km
Cars in the United States are rated in miles per US gallon, while Europe, Canada, Australia, and much of the world use liters per 100 kilometers. Converting mpg to L/100 km helps buyers compare American ratings with international reviews and helps travelers estimate fuel costs abroad.
When you need to convert miles per US gallon to liters per 100 km

Tips for converting miles per US gallon to liters per 100 km
- The two units are reciprocal: higher mpg means fewer liters per 100 km. Divide roughly 235 by mpg to get L/100 km.
- Because of that reciprocal relationship, gains at low mpg matter more: going from 15 to 20 mpg saves more fuel than going from 40 to 50.
- UK mpg uses the larger imperial gallon, so UK figures are about 20% higher than US mpg for the same car; this conversion assumes US gallons.
