Natural gas is a mixture of gases containing approximately 80% methane (CH 4) and its heating value varies from about or 10.1 to 11.4 kilowatt-hours per cubic metre (975 to 1,100 Btu/cu ft), depending on the mix of different gases in the gas stream. The volume of natural gas with heating value of one dekatherm is about 910 to 1,026 cubic feet ...
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).
According to the standard defined by the International Energy Agency, it corresponds in average to 38.2 petajoules (1.06 × 10 10 kWh) of energy in the case of Russian natural gas and 41.4 petajoules (1.15 × 10 10 kWh) of energy in the case of Qatar's natural gas. [1]
Depending on the marketplace, the price of natural gas is often expressed in currency units per volume or currency units per energy content. For example, US dollars or other currency per million British thermal units, thousand cubic feet, or 1,000 cubic meters. Note that, for natural gas price comparisons$, per million Btu multiplied by 1.025 ...
Since natural gas is an imprecise mix of various molecular species, chiefly methane but with varying proportions of other gases, a standard cubic foot of natural gas does not represent a precise unit of mass, but a molecular quantity, expressed in moles.
The value is necessarily approximate as various grades of oil and gas have slightly different heating values. If one considers the lower heating value instead of the higher heating value, the value for one BOE would be approximately 5.4 GJ (see tonne of oil equivalent). Typically 5,800 cubic feet of natural gas is equivalent to
Natural gas burning on a gas stove Burning of natural gas coming out of the ground. Natural gas (also fossil gas, methane gas, and gas) is a naturally occurring compound of gaseous hydrocarbons, primarily methane (95%), [1] small amounts of higher alkanes, and traces of carbon dioxide and nitrogen, hydrogen sulfide and helium.

AMFA specifies the energy content of 100 cubic feet of natural gas to be equal to 0.823 gallons-equivalent of natural gas, and the gallon equivalency of natural gas is considered to have a fuel content, similar to that for alcohol fuels, equal to 0.15 gallons of fuel.
