Conversion Formula
W/(cm²·K) = BTU(IT)/(h·ft²·°F) × 0.0005678263341
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 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).
