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 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.
