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.
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.
