MPGe to kWh/100 Miles Converter

Convert miles per gallon gasoline equivalent (MPGe) to kilowatt-hours per 100 miles for electric vehicle efficiency comparison.

What this tool does

Convert miles per gallon gasoline equivalent (MPGe) to kilowatt-hours per 100 miles for electric vehicle efficiency comparison. Type an amount in miles per gallon gasoline equivalent (MPGe), choose the units, and the tool converts it to kilowatt-hours per 100 miles. It offers 5 electric vehicle efficiency units and also shows the same amount in the others.

Inputs

  • Value: A number.
  • From: Choose one: Kilometer per kilowatt-hour, Mile per kilowatt-hour, Mile per gallon gasoline equivalent (MPGe), Kilowatt-hour per 100 kilometers, Kilowatt-hour per 100 miles. Starts as Mile per gallon gasoline equivalent (MPGe).
  • To: Choose one of the same 5 units as "From". Starts as Kilowatt-hour per 100 miles.

How to use

  1. Enter the amount you want to convert.
  2. Choose the unit to convert from and the unit to convert to.
  3. Read the result: the converted amount and the same amount in the other units. It appears once every required field has a valid value.

Worked examples

Conversions from miles per gallon gasoline equivalent (MPGe) to kilowatt-hours per 100 miles:

  • 1 MPGe = 3,370.5 kWh/100 mi
  • 5 MPGe = 674.1 kWh/100 mi
  • 10 MPGe = 337.05 kWh/100 mi
  • 50 MPGe = 67.41 kWh/100 mi
  • 100 MPGe = 33.705 kWh/100 mi

Divide 3,370.5 by the number of miles per gallon gasoline equivalent (MPGe) to get kilowatt-hours per 100 miles. Both units are exact definitions, so 3,370.5 is the exact factor: 1 MPGe = 3,370.5 kWh/100 mi.

Sources: Mile per gallon gasoline equivalent (MPGe): 40 CFR 600.002 (US EPA). Kilowatt-hour per 100 miles: exact by definition.

Limitations

  • Converts the unit of an efficiency figure only. It does not estimate range, charging losses or running cost.
  • MPGe is based on the EPA figure of 33.705 kWh per US gallon of gasoline. Other sources may round it to 33.7.

FAQs

Q: How do I convert MPGe to kWh/100 mi?
A: Enter the value, keep miles per gallon gasoline equivalent (MPGe) in the From box and kilowatt-hours per 100 miles (kWh/100 mi) in the To box. For example, 100 MPGe is 33.705 kWh/100 mi.
Q: Why does a bigger number mean the opposite here?
A: Km/kWh, mi/kWh and MPGe count distance per unit of energy, so a higher number is more efficient. kWh per 100 km or 100 miles counts energy per distance, so a lower number is more efficient. Converting between the two kinds is a reciprocal, not a fixed multiplier.
Q: How is MPGe defined here?
A: MPGe uses the US EPA definition (40 CFR 600.002): one US gallon of gasoline is equivalent to 33.705 kWh of electricity. It is a US gallon, not an imperial gallon.
Q: Can I convert from kWh/100 mi to MPGe instead?
A: Yes. Swap the From and To boxes. For example, 100 kWh/100 mi is 33.705 MPGe.
