Conversion Formula
kW/(m²·K) = BTU(IT)/(h·ft²·°F) × 0.005678263341
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).
About Kilowatt per square metre kelvin
The kilowatt per square metre kelvin (kW/(m²·K)) equals exactly 1000 W/(m²·K). Characteristic of high-performance industrial applications: nucleate pool boiling of water reaches 5-50 kW/(m²·K), compact plate heat exchangers with liquid-liquid flow achieve 3-8 kW/(m²·K), and jet impingement cooling on metal surfaces can exceed 10 kW/(m²·K). 1 kW/(m²·K) = 10³ W/(m²·K).
