Conversion Factors
The conversion factors cover calculation between weight, volume and calorific measures. They provide data for crude oil, products, natural gas, LNG, electricity and solid fuels.

Units
1 metric tonne = 2204.62 lb.
= 1.1023 short tons
1 kilolitre = 6.2898 barrels
1 kilolitre = 1 cubic metre
1 kilocalorie (kcal) = 4.187 kJ = 3.968 Btu
1 kilojoule (kJ) = 0.239 kcal = 0.948 Btu
1 British thermal unit (Btu) = 0.252 kcal = 1.055 kJ
1 kilowatt-hour (kWh) = 860 kcal = 3600 kJ = 3412 Btu
| Calorific equivalents One tonne of oil equivalent equals approximately : |
| Heat units |
10 million kilocarlories 42 gigajoules
40 million Btu |
| Solid fuels |
1.5 tonnes of hard coal 3 tonnes of lignite |
| Gaseous fuels |
See natural gas and LNG table |
| Electricity |
12 mega watt-hours |
One million tonnes of oil produces about 4400 gigawatt-hours
(=4.4 terawatt hours) of electricity in modern power station. |
1 tonne of ethanol = .57 tonne of oil
1 tonne of biodiesel = .88 tonne of oil
1 barrel of ethanol = .57 barrel of oil
1 barrel of biodiesel = .88 barrel of oil
