About Thermochemical calorie per second per square centimetre per degree Celsius
The thermochemical calorie per second per square centimetre per degree Celsius (cal(th)/(s·cm²·°C)) equals exactly 41840 W/(m²·K) (1 cal(th) = 4.184 J; 1 cm² = 10⁻⁴ m²; 1 °C = 1 K). The CGS unit for very high heat transfer coefficients in plasma-facing components, ablative heat shield characterisation, and shock tube experiments in aerospace research. 1 cal(th)/(s·cm²·°C) = 41840 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).
