KEY: Btu = British thermal unit, U = Data are unavailable.
NOTES: Certificated carriers are domestic operations only. General aviation includes fuel used in air taxi operations, but not commuter operations.
Transit data are preliminary.
The following conversion rates were used:
Jet fuel = 135,000 Btu/gallon
Aviation gasoline = 120,200 Btu/gallon
Compressed natural gas = 138,700 Btu/gallon
Distillate fuel = 138,700 Btu/gallon
Automotive gasoline = 125,000 Btu/gallon
Residual fuel oil = 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.
