Conversion Formula
BTU(IT)/(h·in²·°F) = kcal(th)/(h·cm²·°C) × 14.21383118
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).
About International table BTU per hour per square inch per degree Fahrenheit
The international table BTU per hour per square inch per degree Fahrenheit (BTU(IT)/(h·in²·°F)) equals ≈ 817.67 W/(m²·K) (1 in² = 6.4516×10⁻⁴ m²; 1 °F = 5/9 K). Encountered in US electronics thermal management, semiconductor package datasheets, and heat sink characterisation where contact areas are measured in square inches. 1 BTU(IT)/(h·in²·°F) ≈ 817.67 W/(m²·K).
