About International table BTU per hour per square inch
The international table BTU per hour per square inch (BTU(IT)/(h·in²)) equals 1055.05585262/(3600×6.4516×10⁻⁴) ≈ 454.26 W/m². Used for high heat flux applications such as electronic component cooling, jet engine combustor walls, and nuclear fuel assembly design in US customary units. 1 BTU(IT)/(h·in²) ≈ 454.26 W/m².
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.
