Kilowatt-hours per 100 kilometers to kilometers per kilowatt-hour Converter

What this electric car efficiency conversion is for

Use this page when a measurement is written in kilowatt-hours per 100 kilometers and the next step needs kilometers per kilowatt-hour. The number stays blank until you press Calculate, so a half-typed entry is never mistaken for the answer.

The factor

Electric economy flips the same way fuel economy does. kWh/100 km = 100 ÷ km per kWh. Miles per kWh = km per kWh ÷ 1.609344. MPGe uses the EPA gasoline equivalent of 33.7 kWh per gallon, so MPGe = 33.7 × miles per kWh.

A worked example

15 kilowatt-hours per 100 kilometers are 6.66666667 kilometers per kilowatt-hour. 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.

The reverse conversion is kilometers per kilowatt-hour to kilowatt-hours per 100 kilometers. A nearby pair in the same units is miles per gallon equivalent to kilometers per kilowatt-hour. When the converted number is the input to a job, continue with the EV fuel savings.
