About Joule per cubic metre
The joule per cubic metre (J/m³) is the SI coherent unit for energy density (and equivalently, pressure). It covers a wide range from gas combustion (natural gas ~38 MJ/m³) down to small reaction energies. Numerically equal to the pascal (Pa = N/m² = J/m³). Referenced in ISO 31-4. 1 J/m³ = 10⁻³ kJ/m³ = 1 Pa.
About Megawatt-hour per cubic metre
The megawatt-hour per cubic metre (MWh/m³) equals exactly 3.6 × 10⁹ J/m³. Used in large-scale energy storage infrastructure - pumped hydro, grid-scale battery installations, and thermal storage plants. Petrol ≈ 9.5 MWh/m³, LNG ≈ 6.2 MWh/m³, Li-ion pack ≈ 0.56 MWh/m³. 1 MWh/m³ = 3.6 GJ/m³ = 3600 MJ/m³.
