About International table BTU per second per square foot
The international table BTU per second per square foot (BTU(IT)/(s·ft²)) equals 1055.05585262/0.09290304 ≈ 11357 W/m² (= 3600 × BTU(IT)/(h·ft²)). Used for extreme heat flux: atmospheric re-entry aerodynamic heating, solid rocket nozzle throat, and nuclear reactor thermal hydraulics design. 1 BTU(IT)/(s·ft²) ≈ 11357 W/m².
About International table kilocalorie per hour per square centimetre
The international table kilocalorie per hour per square centimetre (kcal(IT)/(h·cm²)) equals 4186.8/(3600×10⁻⁴) = 11630 W/m² exactly (1 kcal(IT) = 4186.8 J; 1 h = 3600 s; 1 cm² = 10⁻⁴ m²). Used in IT-based thermodynamics for high heat flux surfaces such as boiler tubes. 1 kcal(IT)/(h·cm²) = 11630 W/m².
