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 International table BTU per cubic foot
The international table BTU per cubic foot (BTU(IT)/ft³) equals 1055.05585262 J / (0.3048)³ m³ ≈ 37258.95 J/m³. Standard in US and Canadian gas industry for expressing the gross calorific value of natural gas as distributed (pipeline quality gas ≈ 1000 BTU/ft³). 1 BTU(IT)/ft³ ≈ 37.26 kJ/m³ ≈ 10.35 Wh/m³.
