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).
About Celsius Heat Unit per hour per square foot per degree Celsius
The Celsius heat unit per hour per square foot per degree Celsius (CHU/(h·ft²·°C)) equals ≈ 5.6783 W/(m²·K) - numerically identical to BTU(IT)/(h·ft²·°F). Used in UK and Canadian steam and process engineering; the temperature-interval ratio °F/°C = 5/9 is exactly compensated by the energy ratio CHU/BTU(IT) = 9/5, making both units numerically equal. 1 CHU/(h·ft²·°C) = 1 BTU(IT)/(h·ft²·°F) ≈ 5.6783 W/(m²·K).
