About Thermochemical calorie per second per square centimetre per degree Celsius
The thermochemical calorie per second per square centimetre per degree Celsius (cal(th)/(s·cm²·°C)) equals exactly 41840 W/(m²·K) (1 cal(th) = 4.184 J; 1 cm² = 10⁻⁴ m²; 1 °C = 1 K). The CGS unit for very high heat transfer coefficients in plasma-facing components, ablative heat shield characterisation, and shock tube experiments in aerospace research. 1 cal(th)/(s·cm²·°C) = 41840 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).
