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.
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.
