Conversion Formula
BTU(IT)/(h·ft²·°F) = mW/(m²·K) × 0.0001761101837
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 International table BTU per hour per square foot per degree Fahrenheit
The international table BTU per hour per square foot per degree Fahrenheit (BTU(IT)/(h·ft²·°F)) equals 1055.05585262/(3600×0.09290304×5/9) ≈ 5.6783 W/(m²·K). The dominant heat transfer coefficient unit in US engineering: ASHRAE handbooks, ASTM standards, boiler and heat exchanger design, and building envelope U-values are all commonly tabulated in this unit. 1 BTU(IT)/(h·ft²·°F) ≈ 5.6783 W/(m²·K).
