KEY: Btu = British thermal unit.

a Domestic operations only.

b Includes fuel used in air taxi operations but not commuter operations.

c Light duty vehicle, short wheel base includes passenger cars, light trucks, vans and sport utility vehicles with a wheelbase (WB) equal to or less than 121 inches. Light duty vehicle, long wheel base includes large passenger cars, vans, pickup trucks, and sport/utility vehicles with wheelbases (WB) larger than 121 inches.

d Diesel includes diesel and biodiesel.

e Gasoline and all other nondiesel fuels include gasoline, liquefied petroleum gas, liquefied natural gas, methane, ethanol, bunker fuel, kerosene, grain additive, and other fuel.

NOTES: The following conversion rates were used:

Jet fuel = 135,000 Btu/gallon.

Aviation gasoline = 120,200 Btu/gallon.

Automotive gasoline = 125,000 Btu/gallon.

Diesel motor fuel = 138,700 Btu/gallon.

Compressed natural gas = 138,700 Btu/gallon.

Distillate fuel = 138,700 Btu/gallon.

Residual fuel = 149,700 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.
