About International table kilocalorie per hour per square metre per degree Celsius
The international table kilocalorie per hour per square metre per degree Celsius (kcal(IT)/(h·m²·°C)) equals 4186.8/3600 ≈ 1.1633 W/(m²·K) (1 kcal(IT) = 4186.8 J). The IT variant used in steam turbine, power plant, and process industry engineering. Numerically slightly larger than the thermochemical counterpart. 1 kcal(IT)/(h·m²·°C) ≈ 1.1633 W/(m²·K).
About Thermochemical kilocalorie per hour per square metre per degree Celsius
The thermochemical kilocalorie per hour per square metre per degree Celsius (kcal(th)/(h·m²·°C)) equals 4184/3600 ≈ 1.1622 W/(m²·K) (1 kcal(th) = 4184 J; 1 °C = 1 K). Widely used in continental European and Soviet-era building physics, HVAC standards, and heat exchanger design manuals where wall U-values were tabulated in this unit. 1 kcal(th)/(h·m²·°C) ≈ 1.1622 W/(m²·K).
