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 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).
