About Thermochemical kilocalorie per hour per square metre per degree Celsius
The thermochemical kilocalorie per hour per square metre per degree Celsius (kcal(th)/(h·m²·°C)) equals 4184/3600 ≈ 1.1622 W/(m²·K) (1 kcal(th) = 4184 J; 1 °C = 1 K). Widely used in continental European and Soviet-era building physics, HVAC standards, and heat exchanger design manuals where wall U-values were tabulated in this unit. 1 kcal(th)/(h·m²·°C) ≈ 1.1622 W/(m²·K).
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).
