Coal 1 Ton 28000000
Crude Oil 1 Barrel - 42 gallons 5800000
Fuel Oil no.1 1 Gallon 137400
Fuel Oil no.2 1 Gallon 139600
Fuel Oil no.3 1 Gallon 141800
Fuel Oil no.4 1 Gallon 145100
Fuel Oil no.5 1 Gallon 148800
Fuel Oil no.6 1 Gallon 152400
Diesel Fuel 1 Gallon 139000
Gasoline 1 Gallon 124000
Natural Gas 1 Cubic Foot (cu.ft.) 950 - 1150
Heating Oil 1 Gallon 139000
Kerosene 1 Gallon 135000
Pellets 1 Ton 16500000
Propane LPG (Liquid Petroleum Gas) 1 Gallon 91330
Propane gas 60oF 1 Cubic Foot (cu.ft.) 2550
Residual Fuel Oil 1) 1 Barrel - 42 gallons 6287000
Wood - air dried 1 Cord 20000000

1) Residual Fuel Oil - The liquid or semi-liquid, high-boiling fraction of residue from the distillation of crude oil.

• 1 Gallon (U.S.) = 3.785x10-3 m3 = 3.785 dm3 (liter)
• 1 ft3 = 0.02832 m3
• 1 barrel (US, oil) = 1.33 barrel (US, liq) = 5.61458 cu foot = 42 gallons (US, liq) = 158.9873 liter
• 1 lbm = 0.4536 kg
• 1 ton (short) = 2000 lbs = 907 kg

### Btu - British Thermal Unit

The unit of heat in the imperial system - the BTU - is

• the amount of heat required to raise the temperature of one pound of water through 1oF (58.5oF - 59.5oF) at sea level (30 inches of mercury).
• 1 Btu (British thermal unit) = 1055.06 J = 107.6 kpm = 2.931 10-4 kWh = 0.252 kcal = 778.16 ft lbf = 1.0551010 ergs = 252 cal = 0.293 watt hours

An item using one kilowatt-hour of electricity will generate 3412 Btu.
