The following conversion rates were used:,,,,,,,,,,,
"Jet fuel = 135,000 Btu/gallon",,"Compressed natural gas = 138,700 Btu/gallon",,,,,,,,,
"Aviation gasoline = 120,200 Btu/gallon",,"Distillate fuel = 138,700 Btu/gallon",,,,,,,,,
"Automotive gasoline = 125,000 Btu/gallon",,"Residual fuel = 149,700 Btu/gallon",,,,,,,,,
"Diesel motor fuel = 138,700 Btu/gallon",,"Natural gas = 1,031 Btu/ft3",,,,,,,,,
"Electricity  1kWh = 3,412 Btu, negating electrical system losses. To include approximate electrical system losses, multiply this conversion factor by 3.",,,,,,,,,,,
