The therm (symbol, thm) is a non-SI unit of heat energy equal to 100000 British thermal units (Btu). It is approximately the energy equivalent of burning 100 cubic feet (2.83 cubic metres) – often referred to as 1 CCF – of natural gas. The volume of the gas is calculated as if measured at standard temperature and pressure (STP).

  • Therm (Einheitenzeichen: thm) ist eine angloamerikanische Maßeinheit für die physikalische Größe Energie bzw. Wärmemenge. Sie ist von der British thermal unit (BTU) abgeleitet: * 1 thm = 100.000 BTU = 105,5056 × 106 Joule Ein Therm entspricht etwa 29,3 kWh. Die Einheit wird vor allem im Bereich der internationalen Erdgas-Industrie verwendet, wo Öleinheiten (toe, boe) weniger üblich sind.

  • The therm (symbol, thm) is a non-SI unit of heat energy equal to 100000 British thermal units (Btu). It is approximately the energy equivalent of burning 100 cubic feet (2.83 cubic metres) – often referred to as 1 CCF – of natural gas. Since natural gas meters measure volume and not energy content, a therm factor is used by natural gas companies to convert the volume of gas used to its heat equivalent, and thus calculate the actual energy use. The therm factor is usually expressed in units of therms per CCF. It will vary with the mix of hydrocarbons in the natural gas. Natural gas with a higher than average concentration of ethane, propane or butane will have a higher therm factor. Impurities, such as carbon dioxide or nitrogen, lower the therm factor. The volume of the gas is calculated as if measured at standard temperature and pressure (STP). One therm is equal to about 105.5 megajoules, 25200 kilocalories, or 29.3 kilowatt-hours. One therm can also be provided by about 96.7 cubic feet (2.74 m3) of natural gas. The therm sometimes has been confused with the thermie. The names of both units come from the Greek word for heat.
