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 Milliwatt per square metre kelvin
The milliwatt per square metre kelvin (mW/(m²·K)) equals 10⁻³ W/(m²·K). Used in thermal characterization of advanced superinsulation panels and cryogenic multilayer insulation (MLI) in space applications, where effective heat transfer coefficients as low as 0.5-5 mW/(m²·K) are achieved in high-vacuum multilayer systems. 1 mW/(m²·K) = 10⁻³ W/(m²·K).
