Conversion Formula
W/(m²·K) = cal(IT)/(s·cm²·°C) × 41868
About International table calorie per second per square centimetre per degree Celsius
The international table calorie per second per square centimetre per degree Celsius (cal(IT)/(s·cm²·°C)) equals exactly 41868 W/(m²·K) (1 cal(IT) = 4.1868 J; 1 cm² = 10⁻⁴ m²; 1 °C = 1 K). Slightly larger than the thermochemical variant; used in IT-based thermophysical property tables for extreme thermal environments such as nuclear and fusion reactor surfaces. 1 cal(IT)/(s·cm²·°C) = 41868 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).
