Convert International table BTU per second per square foot per degree Fahrenheit to International table calorie per second per square centimetre per degree Celsius
Convert International table BTU per second per square foot per degree Fahrenheit (BTU(IT)/(s·ft²·°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)/(s·ft²·°F) × 0.4882427636
About International table BTU per second per square foot per degree Fahrenheit
The international table BTU per second per square foot per degree Fahrenheit (BTU(IT)/(s·ft²·°F)) equals ≈ 20442 W/(m²·K) (= 3600 × BTU(IT)/(h·ft²·°F)). Encountered in atmospheric re-entry aerodynamic heating analysis, solid rocket motor nozzle throat design, and nuclear reactor thermal-hydraulics with peak surface heat transfer rates. 1 BTU(IT)/(s·ft²·°F) ≈ 20442 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).
