Natural Gas Volume and Energy Content
1,000,000 m3 of natural gas is approximately equivalent to an energy content of 10.36 GWh. This is based on an indicative 0.0373 gigajoules per m3.
Conversely, 1 TWh is approximately equivalent to 96.5 million m3 of natural gas.
Moreover, 1 TWh equates to 3.6 petajoules of energy.
LNG Energy Content
One cubic meter of LNG is very roughly equivalent to (conservative) 20 gigajoules (GJ), depending on the source of gas and the process that is used to liquefy the gas. The Canada Energy Regulator implies an indicative range of 18.3-25.5 GJ.
