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 Kilojoule per cubic metre
The kilojoule per cubic metre (kJ/m³) equals exactly 1000 J/m³. Common in gas industry and HVAC for expressing the volumetric heating value of fuel gases: natural gas ~35-38 MJ/m³, biogas ~20-25 MJ/m³, hydrogen ~10.8 MJ/m³ (standard conditions). 1 kJ/m³ = 1000 J/m³ = 1 Wh/(277.8 m³).
