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 Thermochemical kilocalorie per cubic metre
The thermochemical kilocalorie per cubic metre (kcal(th)/m³) equals exactly 4184 J/m³ (1 kcal(th) = 4184 J). Used in older continental European and Russian engineering references for volumetric heating values of gases and process heat. 1 kcal(th)/m³ = 4184 J/m³ ≈ 1.162 Wh/m³.
