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 ...
A decatherm is 10 therms or one million Btu. ... As a coarse approximation, 1,000 cubic feet (28 m 3) of natural gas yields ≈ 1,000,000 Btu ≈ 1 GJ.
standard cubic foot: scf (scfoot) scf long code "scfoot and cufootatm" outputs standard cubic foot and cubic foot of atmosphere respectively (and never feet) 1.0 scf (2.9 kJ) cuftatm [convert: unknown unit] cuftatm (cufootatm) (none) impgalatm [convert: unknown unit] impgalatm (none) 1.0 impgalatm [convert: unknown unit] USgalatm [convert ...
For rough comparisons, one million Btu is approximately equal to a thousand cubic feet of natural gas. [8] Pipeline-quality gas has an energy value slightly higher than that of pure methane, which has 10.47 kilowatt-hours per cubic metre (1,012 British thermal units per cubic foot).
Therm (thm) – unit of heat energy. In the US gas industry it is defined as exactly 100,000 BTU 59 °F. It is approximately the heat equivalent of burning 100 cubic feet (2.8 m 3) of natural gas (~105.5 MJ). Quad – unit of energy equal to 10 15 (a short-scale quadrillion) BTU.
One GGE of natural gas is 126.67 cubic feet (3.587 m 3) at standard conditions. This volume of natural gas has the same energy content as one US gallon of gasoline (based on lower heating values : 900 BTU/cu ft (9.3 kWh/m 3 ) of natural gas and 114,000 BTU/US gal (8.8 kWh/L) for gasoline).
Coal or coke oven gas typically had a calorific value between 10 and 20 megajoules per cubic metre ... millions of therms. ... million cubic feet: 29,634 35,149 ...
This regulation defines a standard cubic foot, for compressed or liquefied gases in refillable cylinders other than LPG by, "A standard cubic foot of gas is defined as a cubic foot at a temperature of 21 °C (70 °F) and a pressure of 101.325 kilopascals [kPa] (14.696 psia)".
