Convert kilometers per kilowatt-hour to miles per kilowatt-hour and mi/kWh to km/kWh. Electric vehicle efficiency converter.
Multiply the km/kWh value by 0.621371 to get miles per kilowatt-hour. This is the same factor used for any kilometer-to-mile conversion since the energy unit stays the same.
| km/kWh | mi/kWh |
|---|---|
| 3 | 1.86 |
| 4 | 2.49 |
| 5 | 3.11 |
| 5.5 | 3.42 |
| 6 | 3.73 |
| 7 | 4.35 |
| 8 | 4.97 |
| 9 | 5.59 |

km/kWh measures electric vehicle efficiency, showing how many kilometers an EV can travel per kilowatt-hour of battery energy. Higher is better.
Efficient EVs achieve 6-7 km/kWh (3.7-4.3 mi/kWh). Larger electric SUVs may get 4-5 km/kWh, while small city EVs can exceed 8 km/kWh.
MPGe (miles per gallon equivalent) is a different metric that compares EV energy use to gasoline. km/kWh and mi/kWh directly measure electric efficiency without gasoline equivalency.
It is simply the kilometers-to-miles conversion factor. Since the energy unit (kWh) is the same on both sides, only the distance unit changes.
