How can I convert EV energy use (kWh/100 miles) into MPGe?
Converting kWh/100 Miles to MPGe
The EPA defines 1 gallon of gasoline as equivalent to 33.7 kWh of energy. To calculate MPGe:
- Formula:
MPGe = (33.7 ÷ kWh per 100 miles) × 100
Example: An EV that uses 28 kWh/100 mi:(33.7 ÷ 28) × 100 ≈ 120 MPGe
This helps compare EV efficiency directly to gasoline cars.
