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).
About International table kilocalorie per hour per square centimetre per degree Celsius
The international table kilocalorie per hour per square centimetre per degree Celsius (kcal(IT)/(h·cm²·°C)) equals 4186.8/0.36 = 11630 W/(m²·K) exactly (1 kcal(IT) = 4186.8 J; 1 h = 3600 s; 1 cm² = 10⁻⁴ m²; 1 °C = 1 K). Used in IT-based thermodynamic tables for boiler tube surfaces and high-temperature process heat exchangers. 1 kcal(IT)/(h·cm²·°C) = 11630 W/(m²·K).
