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 Millijoule per cubic metre
The millijoule per cubic metre (mJ/m³) equals 10⁻³ J/m³. Used in radiation physics for describing energy densities of laser pulses in large volumes and in some acoustic energy density contexts. 1 mJ/m³ = 10⁻³ J/m³ = 10³ µJ/m³.
