WebLiquefied natural gas (LNG) is essentially a methane gas mixture that has been cooled to the point that it becomes a liquid. At atmospheric pressure, this phase transition happens at around −162 °C thus making it a cryogenic liquid. LNG has a density of around 430 kg/m³ to 480 kg/m³ and a gross calorific value of around 54 MJ/kg to 56 MJ ... WebEnter the value you want to convert (normal cubic meter of natural gas).
