How it works
Convert fuel economy between explicitly labeled units.
THE CALCULATIONL/100 km = 100/(km/L) = 235.214583/(US mpg) = 282.480936/(Imperial mpg)
Using this calculator
Enter value, from unit, to unit. L/100 km = 100/(km/L) = 235.214583/(US mpg) = 282.480936/(Imperial mpg).
What to keep in mind
Select source and destination units. Prefixes and named unit systems are explicit; displayed results are rounded. This is a unit conversion, not an engineering design assessment. Consumption and efficiency are reciprocal, so inputs must be positive.

Are my entries saved?
No. Calculator inputs remain in the current page and are cleared when you reload or leave. The tools do not upload your entries.
Why are results rounded?
The display is rounded for readability. Calculations use unrounded intermediate values. An estimate should not be interpreted as an exact measurement.
