About International table kilocalorie per hour per square centimetre per degree Celsius
The international table kilocalorie per hour per square centimetre per degree Celsius (kcal(IT)/(h·cm²·°C)) equals 4186.8/0.36 = 11630 W/(m²·K) exactly (1 kcal(IT) = 4186.8 J; 1 h = 3600 s; 1 cm² = 10⁻⁴ m²; 1 °C = 1 K). Used in IT-based thermodynamic tables for boiler tube surfaces and high-temperature process heat exchangers. 1 kcal(IT)/(h·cm²·°C) = 11630 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).
