Conversion Factors:
Volume/weight/mass
1,000 ft3 = 28.3 m3
Cubic feet X 0.02831685 = cubic meters
1 cubic meter = 1,000 liters = 35.31 cubic feet
1 gallon = 3.785 liters
1 barrel = 42 gallons = 159.0 liters
Barrels X 0.1589873 = cubic meters
1 kilogram = 2.205 pounds
1 pound = 0.4536 kilograms
1 short ton = 0.9072 metric tonne
1 metric ton = 2205 pounds

Energy
1 Btu = 252.0 calories = 1055 joules
1000 joules = 0.9479 Btu
1 joule = 0.2388 calories
1 calorie = 4.187 joules
1 kilowatthour = 3.600 x 106 joules = 3,412 Btu
1 quad = 1015 Btu = 2.931 x 1011 kilowatthours
1 therm = 100,000 Btu

Power
1 watt = 1 joule/sec = 3.412 Btu/hr
1 Btu/hr = 0.2931 watts
1 kilowatt = 0.9478 Btu/sec = 1.341 horsepower
1 Btu/sec = 1.055 kilowatts
1 horsepower = 0.7068 Btu/sec = 0.7457 kilowatts

Pressure
1 psi = 6.9 kilopascals

Other:
1 bbl oil = 1700 kw hr = 6120 X 106 joules
1000 ft3 gas = 300 kw hr = 1080 X 106 joules
1 metric ton peat = 5370 kw hr = 19,332 X 106 joules
1 short ton coal = 0.9078 metric ton = 6600 kw hr = 23,760 X 106 joules
1 metric ton of oil = 7.64 barrels for oil with API gravity of 40°
