"NOTES:  The heat equivalent factors used in Btu conversions are: diesel = 138,700 Btu/gallon; electric = 3,412 Btu/kWh,  ",,,,,,,,,,,,,,,
"negating electrical system loses (to include electrical system loses, multiply this conversion factor by approximately three) gasoline = 125,000 Btu/gallon. ",,,,,,,,,,,,,,
