About International table BTU per second per square foot per degree Fahrenheit
The international table BTU per second per square foot per degree Fahrenheit (BTU(IT)/(s·ft²·°F)) equals ≈ 20442 W/(m²·K) (= 3600 × BTU(IT)/(h·ft²·°F)). Encountered in atmospheric re-entry aerodynamic heating analysis, solid rocket motor nozzle throat design, and nuclear reactor thermal-hydraulics with peak surface heat transfer rates. 1 BTU(IT)/(s·ft²·°F) ≈ 20442 W/(m²·K).
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).
