# Mile Per Gallon Gasoline Equivalent (MPGe) Converters

> Convert MPGe to and from miles per kWh, km per kWh, kWh per 100 miles, kWh per 100 km, and other EV efficiency units

**Category:** Conversion
**Keywords:** MPGe, miles per gallon equivalent, electric vehicle, EV, kWh, efficiency, fuel economy, convert

## How it calculates

The core conversion factor is that 1 US gallon of gasoline contains 33.705 kWh of energy. From this: miles per kWh = MPGe / 33.705, kWh per 100 miles = 3370.5 / MPGe, and km per kWh = MPGe / (33.705 / 1.60934). Consumption-based units like kWh per 100 miles have an inverse relationship with efficiency-based units, requiring division rather than multiplication. The tool converts all inputs to MPGe as an intermediate base unit before converting to the target unit.

## Who should use this

- **EV buyers** comparing efficiency ratings across different electric vehicle models
- **Fleet managers** evaluating operational costs of electric vs gasoline fleets
- **Energy analysts** standardizing EV efficiency data across international markets
- **Environmental researchers** calculating emissions savings from vehicle electrification

## Worked examples

Example 1: A Tesla Model 3 rated at 132 MPGe converts to miles per kWh: 132 / 33.705 = 3.917 miles/kWh. Example 2: Converting 132 MPGe to kWh per 100 miles: 3370.5 / 132 = 25.53 kWh/100mi. Example 3: An EV consuming 15 kWh/100km converts to MPGe: 3370.5 / (15 × 1.60934) = 139.6 MPGe.

## Limitations

MPGe is based on the EPA's defined energy content of gasoline (33.705 kWh per gallon), which is a standardized value. Actual gasoline energy content varies slightly by blend and season. This tool does not account for charging losses, which typically add 10-15% to actual energy consumption. Real-world EV efficiency varies significantly with temperature, speed, terrain, and use of climate control systems.

## FAQs

**Q:** What does MPGe actually measure?


**A:** MPGe measures how far an electric vehicle can travel on the amount of electricity equivalent to the energy in one gallon of gasoline (33.705 kWh). A 100 MPGe rating means the vehicle travels 100 miles on 33.705 kWh.


**Q:** Why do some EVs show kWh/100 miles instead of MPGe?


**A:** Both metrics appear on EPA window stickers. kWh/100 miles is a consumption metric (lower is better), while MPGe is an efficiency metric (higher is better). Many drivers find kWh/100 miles more practical for estimating charging costs.


**Q:** How does MPGe relate to real electricity costs?


**A:** Divide the kWh/100 miles value by 100, then multiply by your electricity rate. For example, 30 kWh/100 miles at $0.12/kWh costs $3.60 per 100 miles.


**Q:** Is a higher or lower MPGe better?


**A:** Higher MPGe is better, just like higher MPG for gasoline vehicles. It means the vehicle travels more miles per unit of energy consumed.
