If more carbon atoms are in the hydrogen gas, the value of Btu is higher. The amount of energy of natural gas can be converted from Btu per cubic feet to Joules per cubic meter. If 1 Btu equals 1055.1 J and 1 ft 3 equals 0.028316 m 3, then 1000 Btu/ft 3 multiplied by 1055.1 J and divided by 0.028316 m 3 equals 37 MJ/m 3, which is the average energy content of natural gas.

For natural gases, the energy density is the either the amount of energy stored per unit volume or per unit mass of the gas. The energy stored per unit volume is usually measured in British Thermal Units per cubic feet, or, the amount of natural gas that will produce enough energy to heat one pound of water one degree at normal pressure.

Natural gas energy density At standard pressure (0.1013 mPascal) and temperature (293 K), the density of natural gas is 0.717 kg/m3. Natural gas contains methane, nitrogen, oxygen and various other constituents. Methane is the key constituent of natural gas.

This calculator determines the mass density of natural gas using the AGA8 detailed characterization equation (i.e. AGA8-92DC). It is valid subject to the following conditions: Absolute pressure: 0 MPa ≤ p ≤ 65 MPa; Temperature: 225 K ≤ T ≤ 350 K; Superior calorific value: 20 MJ/m³ ≤ H S ≤ 48 MJ/m³; Relative density: 55% ≤ d ≤ 90%

Natural gas should be technically exempt, that is, there should be no visible traces of solid and liquid particles. Specification limits are values referred to as 293.15 K (20 ºC) and 101.325 kPa (1 atm) on a dry base, except at dew point.
