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 US gallon
The international table BTU per US gallon (BTU(IT)/gal(US)) equals 1055.05585262 J / 3.785411784 × 10⁻³ m³ ≈ 278716.27 J/m³. The dominant unit in the US petroleum and fuel markets for expressing heating values - gasoline ≈ 115,000 BTU/gal, diesel ≈ 129,500 BTU/gal. 1 BTU(IT)/gal(US) ≈ 278.72 kJ/m³.
