Fuel consumption converter
Convert L/100 km, km/L, US mpg and UK mpg.
This tool lets you compare fuel consumption in liters per 100 km, kilometers per liter and miles per gallon.

Approximation
Quick explanation
Enter a positive fuel consumption value, then choose the source and target units.
Some units are inverse: a small L/100 km value corresponds to a large mpg value.

Convert speed
For km/h, mph and knots, use the speed converter.
Additional information
Why is this conversion special?
L/100 km measures fuel used for a given distance. mpg and km/L measure distance traveled for a quantity of fuel. The conversion is therefore inverse.
US mpg and UK mpg
The US gallon and the imperial UK gallon do not have the same volume. It is normal for US mpg and UK mpg to give different results.
What does 0 L/100 km mean?
Zero consumption would imply infinite distance in inverse units. The tool therefore avoids division by zero.
