Units

1 metric tonne = 2204.62lb = 1.1023 short tons
1 kilolitre = 6.2896 barrels = 1 cubic metre
1 kilocalorie (kcal) = 4.187kj = 3.968Btu
1 kilojoule (kJ) = 0.239kcal = 0.948Btu
1 British thermal unit (Btu) = 0.252kcal = 1.055kJ
1 kilowatt-hour (kWh) = 860kcal = 3600kJ = 3412Btu

Calorific equivalents

One tonne of oil equivalent equals approximately

Heat units           

10 million kilocalories
42 gigajoules
40 million British thermal units

Solid fuels          

1.5 tonnes of hard coal
3 tonnes of lignite

Gaseous fuels  

See Natural gas and liquefied natural gas table

Electricity            

12 megawatt-hours
One million tonnes of oil or oil equivalent produces about 4400 gigawatt-hours (=4.4 terawatt-hours) of electricity in a modern power station.
