Using Test case with statically assigned variables for the moment:
http://www.eaa-phev.org/wiki/Image:Capture0060.png
28 miles on 15.495 kWh is 1.807 mi/kWh or 61 MPGe.
28 miles @ 78.5 mpg is 0.357 gal. of gas,
Equal to 11.995 kWh of electricity, @33.6 kWh/gal
Plus the 3.5 kWh used charged for 15.495 kWh total energy.

Use Examples

Template to convert fuel mileage from various fuels or combinations of fuels into MPGe Miles per Gallon of Gasoline Equivalent.

  • {{mpge|miles=50.00|kWh=10.00}} results in XX mpge
  • {{mpge|km=80.00|kWh=10.00}} results in XX mpge
  • {{mpge|miles=50.00|kWh=10.00|metric=on}} results in XX mpge
  • {{mpge|miles=50.00|kWh=10.00|imperial=on}} results in XX mpge
  • {{mpge|miles=50.00|gas=1.000}} results in XX mpge
  • {{mpge|miles=50.00|diesel=1.000|lk=on}} results in XX mpge
  • {{mpge|L100km=50}} results in XX mpge
  • {{mpge|mpg=50}} results in XX mpge

Per BMW Tops Toyota Prius In Fuel Economy Tests which claims the BMW 520d got 41.9 mpg(diesel) while the Prius got 40.1 mpg(gas). However the energy content of gas and diesel fuels differ, so we can adjust the diesel into an mpge equivalent XX mpge 41.9mpg(diesel) * 0.88 = 36.872 mpge versus the 40.1mpge of the Prius.
