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 International table kilocalorie per hour per square metre per degree Celsius
The international table kilocalorie per hour per square metre per degree Celsius (kcal(IT)/(h·m²·°C)) equals 4186.8/3600 ≈ 1.1633 W/(m²·K) (1 kcal(IT) = 4186.8 J). The IT variant used in steam turbine, power plant, and process industry engineering. Numerically slightly larger than the thermochemical counterpart. 1 kcal(IT)/(h·m²·°C) ≈ 1.1633 W/(m²·K).
