Convert International table BTU per hour per square inch per degree Fahrenheit to International table calorie per second per square centimetre per degree Celsius
Convert International table BTU per hour per square inch per degree Fahrenheit (BTU(IT)/(h·in²·°F)) to International table calorie per second per square centimetre per degree Celsius (cal(IT)/(s·cm²·°C)) instantly and accurately.
Conversion Formula
cal(IT)/(s·cm²·°C) = BTU(IT)/(h·in²·°F) × 0.01952971055
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 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).
