What this fuel economy conversion is for

Use this page when a measurement is written in miles per gallon and the next step needs kilometers per liter. 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

30 miles per gallon are 12.75431122 kilometers per liter. Multiply the result by the reverse factor if you want the original number back.

How to check it

Write the factor down, do the multiply on paper, and compare it with the result card. If you change a sentence on this page, edit the HTML file and reload. The form and this note live in the same file.
