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 calorie per cubic centimetre
The thermochemical calorie per cubic centimetre (cal(th)/cm³) equals exactly 4.184 × 10⁶ J/m³ (1 cal(th) = 4.184 J; 1 cm³ = 10⁻⁶ m³). The CGS energy density unit used extensively in older chemistry, explosives research, and combustion science for solid and liquid fuels. Numerically equal to kcal(th)/L. 1 cal(th)/cm³ = 4.184 MJ/m³.
