About International table BTU per hour per square foot per degree Fahrenheit
The international table BTU per hour per square foot per degree Fahrenheit (BTU(IT)/(h·ft²·°F)) equals 1055.05585262/(3600×0.09290304×5/9) ≈ 5.6783 W/(m²·K). The dominant heat transfer coefficient unit in US engineering: ASHRAE handbooks, ASTM standards, boiler and heat exchanger design, and building envelope U-values are all commonly tabulated in this unit. 1 BTU(IT)/(h·ft²·°F) ≈ 5.6783 W/(m²·K).
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).
