Conversion Formula
BTU(IT)/(s·ft²·°F) = cal(IT)/(s·cm²·°C) × 2.048161436
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 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).
