How to convert fuel economy

Select your starting and destination units, enter a value, and the result appears automatically. You can also enter a value in the right-hand field to convert in reverse.

Conversions use a shared reference unit, with the appropriate factor applied for each selected unit.

For critical engineering, legal or medical work, verify rounding and applicable measurement standards independently.
