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 Thermochemical kilocalorie per hour per square centimetre per degree Celsius
The thermochemical kilocalorie per hour per square centimetre per degree Celsius (kcal(th)/(h·cm²·°C)) equals ≈ 11622 W/(m²·K) (= 10⁴ × kcal(th)/(h·m²·°C)). A high-flux CGS metric unit found in older combustion engineering, industrial furnace design, and metallurgical heat treating references. 1 kcal(th)/(h·cm²·°C) ≈ 11622 W/(m²·K).
