About Celsius Heat Unit per hour per square foot per degree Celsius
The Celsius heat unit per hour per square foot per degree Celsius (CHU/(h·ft²·°C)) equals ≈ 5.6783 W/(m²·K) - numerically identical to BTU(IT)/(h·ft²·°F). Used in UK and Canadian steam and process engineering; the temperature-interval ratio °F/°C = 5/9 is exactly compensated by the energy ratio CHU/BTU(IT) = 9/5, making both units numerically equal. 1 CHU/(h·ft²·°C) = 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).
