Convert an EV's watt-hours per mile into MPGe and miles per kWh.
MPGe expresses how far an EV would travel on the energy content of one gallon of gasoline, which is 33.7 kWh. MPGe and miles per kWh let you compare an EV against a gas car and against other EVs regardless of drivetrain.
MPGe Efficiency
MPGe = 33.7 kWh / (Wh per mile / 1000)
MPGe = 33.7 kWh / (Wh per mile / 1000) MPGe expresses how far an EV would travel on the energy content of one gallon of gasoline, which is 33.7 kWh.
MPGe and miles per kWh let you compare an EV against a gas car and against other EVs regardless of drivetrain.
