Conversion Formula
BTU(IT)/(s·ft²·°F) = cal(th)/(h·cm²·°C) × 0.0005685532473
About Thermochemical calorie per hour per square centimetre per degree Celsius
The thermochemical calorie per hour per square centimetre per degree Celsius (cal(th)/(h·cm²·°C)) equals 4.184/0.36 ≈ 11.622 W/(m²·K) (1 cal(th) = 4.184 J; 1 cm² = 10⁻⁴ m²). A CGS-derived unit found in older heat transfer textbooks and chemical engineering publications, especially in Eastern European and Japanese technical literature. 1 cal(th)/(h·cm²·°C) ≈ 11.622 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).
