About the Fuel Economy Converter

Fuel Economy Converter handles reciprocal consumption and efficiency units correctly. It uses the US gallon definition for mpg and labels it to prevent confusion with imperial mpg.

How to use the Fuel Economy Converter

  1. Enter a positive fuel-economy value.
  2. Select its current unit and desired unit.
  3. Convert and compare vehicles using one consistent unit.

Practical tips

  • Lower L/100 km is better, while higher km/L or mpg is better.
  • Real consumption varies with route, load, maintenance and driving style.
