kWh/100mi to MPGe Converter

Convert kilowatt-hours per 100 miles to miles per gallon gasoline equivalent (MPGe).

What this tool does

Convert kilowatt-hours per 100 miles to miles per gallon gasoline equivalent (MPGe). Type an amount in kilowatt-hours per 100 miles, choose the units, and the tool converts it to miles per gallon gasoline equivalent (MPGe). 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 Kilowatt-hour per 100 miles.
  • To: Choose one of the same 5 units as "From". Starts as Mile per gallon gasoline equivalent (MPGe).

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

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

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

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

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 kWh/100 mi to MPGe?
A: Enter the value, keep kilowatt-hours per 100 miles (kWh/100 mi) in the From box and miles per gallon gasoline equivalent (MPGe) in the To box. For example, 30 kWh/100 mi is 112.35 MPGe.
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 MPGe to kWh/100 mi instead?
A: Yes. Swap the From and To boxes. For example, 30 MPGe is 112.35 kWh/100 mi.
