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).
About Watt per square metre kelvin
The watt per square metre kelvin (W/(m²·K)) is the SI coherent unit for heat transfer coefficient (ISO 80000-5). Typical values: free convection in still air 2-25 W/(m²·K), forced-air cooling 25-250 W/(m²·K), natural water convection 200-1000 W/(m²·K), forced water up to 10 000 W/(m²·K), nucleate boiling up to 100 000 W/(m²·K). 1 W/(m²·K) = 1 J/(s·m²·K).
