Convert Thermochemical kilocalorie per hour per square centimetre to International table BTU per second per square foot
Convert Thermochemical kilocalorie per hour per square centimetre (kcal(th)/(h·cm²)) to International table BTU per second per square foot (BTU(IT)/(s·ft²)) instantly and accurately.
Conversion Formula
BTU(IT)/(s·ft²) = kcal(th)/(h·cm²) × 1.023395845
About Thermochemical kilocalorie per hour per square centimetre
The thermochemical kilocalorie per hour per square centimetre (kcal(th)/(h·cm²)) equals 4184/(3600×10⁻⁴) ≈ 11622 W/m² (= 10⁴ × kcal(th)/(h·m²)). A high-flux variant of the metric heat flux unit found in older combustion engineering and furnace design references. 1 kcal(th)/(h·cm²) ≈ 11622 W/m².
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.
