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).
About Thermochemical calorie per hour per square centimetre per degree Celsius
The thermochemical calorie per hour per square centimetre per degree Celsius (cal(th)/(h·cm²·°C)) equals 4.184/0.36 ≈ 11.622 W/(m²·K) (1 cal(th) = 4.184 J; 1 cm² = 10⁻⁴ m²). A CGS-derived unit found in older heat transfer textbooks and chemical engineering publications, especially in Eastern European and Japanese technical literature. 1 cal(th)/(h·cm²·°C) ≈ 11.622 W/(m²·K).
