1 therm is defined in the United States as 100,000 Btu using the Btu 59 °F definition. In the EU it was listed in 1979 with the BTU IT definition and planned to be discarded as a legal unit of trade by 1994. [21] United Kingdom regulations were amended to replace therms with joules with effect from 1 January 2000. [22]
The therm (symbol, thm) is a non-SI unit of heat energy equal to 100,000 British thermal units (BTU), [1] and approximately 105 megajoules, 29.3 kilowatt-hours, 25,200 kilocalories and 25.2 thermies. One therm is the energy content of approximately 100 cubic feet (2.83 cubic metres) of natural gas at standard temperature and pressure. However ...

Natural gas is often sold in units of energy content or by volume. Common units for selling by energy content are joules or therms. One therm is equal to about 1,055 megajoules. Common units for selling by volume are cubic metre or cubic feet. Natural gas in the US is sold in therms or 100 cubic feet (100 ft 3). In Australia, natural gas is ...
