What does 'miles per kilowatt hour (mi/kWh)' mean?

Miles per kilowatt hour (mi/kWh) is a measure of how efficiently an electric car uses energy. 4mi/kWh is generally considered efficient.

It breaks down how far (in miles) a car can travel per unit of electricity (kilowatt hour, or kWh) of battery capacity. And, just like miles per gallon (mpg), the higher the number, the more efficient the car.

It’s the most commonly used measurement for electric car efficiency in the UK, with some European nations and America preferring other metrics.
