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.
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).
