How it works

The tool works by using reciprocal fuel-economy equations with separate US and imperial gallon constants. Conversion runs locally in the browser, and entered values are not sent to analytics or stored in the database.
Examples
Practical example
10 L/100 km converts to about 23.52 US mpg.
