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).
About International table calorie per hour per square centimetre per degree Celsius
The international table calorie per hour per square centimetre per degree Celsius (cal(IT)/(h·cm²·°C)) equals 4.1868/0.36 = 11.63 W/(m²·K) (1 cal(IT) = 4.1868 J). The IT variant of the CGS heat transfer unit, encountered in steam engineering references and international process industry tables alongside kcal(IT)-based figures. 1 cal(IT)/(h·cm²·°C) = 11.63 W/(m²·K).
