  2. Therm - Wikipedia

    en.wikipedia.org/wiki/Therm

    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 ...

    en.wikipedia.org/wiki/British_thermal_unit

    The British thermal unit (Btu) is a measure of heat, which is a form of energy. ... 1,000 cubic feet (28 m 3) of natural gas yields ≈ 1,000,000 Btu ≈ 1 GJ.

  4. Units of energy - Wikipedia

    en.wikipedia.org/wiki/Units_of_energy

    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 sold in cubic metres. One cubic metre contains about 38 megajoules.

  6. Cubic foot - Wikipedia

    en.wikipedia.org/wiki/Cubic_foot

    The IEEE symbol for the cubic foot per second is ft 3 /s. [1] The following other abbreviations are also sometimes used: ft 3 /sec; cu ft/s; cfs or CFS; cusec; second-feet; The flow or discharge of rivers, i.e., the volume of water passing a location per unit of time, is commonly expressed in units of cubic feet per second or cubic metres per second.

  7. Gasoline gallon equivalent - Wikipedia

    en.wikipedia.org/wiki/Gasoline_gallon_equivalent

    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). [22]

    For measuring length, the U.S. customary system uses the inch, foot, yard, and mile, which are the only four customary length measurements in everyday use. From 1893, the foot was legally defined as exactly 1200 ⁄ 3937 m (approximately 0.304 8006 m). [13] Since July 1, 1959, the units of length have been defined on the basis of 1 yd = 0.9144 ...
