1 Approximate conversion factors Statistical Review of World Energy Approximate conversion factors Statistical Review of World Energy updated July 2021 Page | 1 Crude oil* To convert Tonnes (metric) Kilolitres Barrels US gallons Tonnes/year From Multiply by Tonnes (metric) 1 Kilolitres 1 Barrels 1 42 US gallons 1 Barrels/day *Based on the worldwide average gravity Products To convert Barrels to tonnes Tonnes to barrels Kilolitres to tonnes Tonnes to kilolitres Tonnes to gigajoules Tonnes to barrels oil equivalent From Multiply by Ethane Liquified petroleum gas (LPG) Gasoline Kerosene Gas oil/diesel Residual fuel oil Product basket Approximate conversion factors Statistical Review of World Energy updated July 2021 Page | 2 Natural gas and LNG To convert Billion cubic metres NG Billion cubic feet NG Petajoules NG Million tonnes oil equivalent Million tonnes LNG Trillion British thermal units Million barrels oil equivalent From Multiply by 1 billion cubic metres NG 1 billion cubic feet NG 1 petajoule NG 1 million tonnes oil equivalent 1 million tonnes LNG 1 trillion
2 British thermal units 1 million barrels oil equivalent Units 1 metric tonne = lb = short tons 1 kilolitre = barrels 1 kilolitre = 1 cubic metre 1 kilocalorie (kcal) = kJ = Btu 1 kilojoule (kJ) = kcal = Btu 1 petajoule (Pj) = 1 quadrillion joules (1 x 1015) Approximate conversion factors Statistical Review of World Energy updated July 2021 Page | 3 Units 1 exajoule (EJ) = 1 quintillion joules (1 x 1018) 1 British thermal unit (Btu) = kcal = kJ 1 tonne of oil equivalent (toe) = million Btu = million kJ 1 barrel of oil equivalent (boe) = million Btu = million kJ 1 kilowatt hour (kWh) = 860 kcal = 3412 Btu = 3600 kJ Calorific equivalents One exajoule equals approximately Heat units 239 trillion kilocalories 948 trillion Btu Solid fuels 40 million tonnes of hard coal 95 million tonnes of lignite and sub-bituminous coal Gaseous fuels See natural gas and LNG table Electricity 278 terawatt hours Approximate conversion factors Statistical Review of World Energy updated July 2021 Page | 4 All fuel energy content is net or lower heating value ( , net of heat of vaporisation of water generated from combustion)
3 Thermal equivalent efficiency factors used to convert non-fossil electricity to primary energy 1 barrel of ethanol = barrels of oil of oil equivalent Year Efficiency factor (%) Year Efficiency factor (%) 1 barrel of biodiesel = barrels of oil of equivalent 1965-2000 2011 1 tonne of ethanol = tonne of oil equivalent 2001 2012 1 tonne of biodiesel = tonne of oil of equivalent 2002 2013 2003 2014 Other terms 2004 2015 Tonnes = metric equivalent of tons 2005 2016 2006 2017 2007 2018 2008 2019 2009 2020 2010
