What this fuel economy conversion is for

Use this page when a measurement is written in kilometers per liter and the next step needs miles per gallon (UK). The number stays blank until you press Calculate, so a half-typed entry is never mistaken for the answer.

The factor

Miles per gallon and liters per 100 kilometers run in opposite directions. US L/100km = 235.215 ÷ mpg. UK gallons are larger, so UK L/100km = 282.481 ÷ mpg. Kilometers per liter = 100 ÷ L/100km.

A worked example

8 kilometers per liter are 22.59847491 miles per gallon (UK). Multiply the result by the reverse factor if you want the original number back.
