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 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).
