Conversion Formula
BTU(IT)/(h·in²·°F) = cal(IT)/(s·cm²·°C) × 51.20403591
About International table calorie per second per square centimetre per degree Celsius
The international table calorie per second per square centimetre per degree Celsius (cal(IT)/(s·cm²·°C)) equals exactly 41868 W/(m²·K) (1 cal(IT) = 4.1868 J; 1 cm² = 10⁻⁴ m²; 1 °C = 1 K). Slightly larger than the thermochemical variant; used in IT-based thermophysical property tables for extreme thermal environments such as nuclear and fusion reactor surfaces. 1 cal(IT)/(s·cm²·°C) = 41868 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).
