About Gigajoule per cubic metre
The gigajoule per cubic metre (GJ/m³) equals exactly 10⁹ J/m³. Used for the energy density of high-energy-density materials and liquefied fuels: LNG ≈ 22.2 GJ/m³, liquid hydrogen ≈ 8.49 GJ/m³, petrol ≈ 34.2 GJ/m³. Also useful for large-scale thermal energy storage reservoirs. 1 GJ/m³ = 10³ MJ/m³ = 10⁹ J/m³.
About Megajoule per cubic metre
The megajoule per cubic metre (MJ/m³) equals exactly 10⁶ J/m³. The practical SI unit for fuel energy density: natural gas ≈ 35-40 MJ/m³, hydrogen (liquid) ≈ 8490 MJ/m³, diesel ≈ 34,200 MJ/m³. Numerically equal to kJ/L and widely used in fuel standards and energy audits. 1 MJ/m³ = 10⁶ J/m³ = 1 kJ/L.
