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 Watt per square centimetre kelvin

The watt per square centimetre kelvin (W/(cm²·K)) equals exactly 10⁴ W/(m²·K). Relevant for extreme cooling: nuclear reactor fuel rod cladding surfaces reach up to 5 W/(cm²·K), spray cooling and microjet impingement in power electronics reach 1-10 W/(cm²·K), and condensation of refrigerants can approach 1 W/(cm²·K). 1 W/(cm²·K) = 10⁴ W/(m²·K) = 10 kW/(m²·K).
