About Thermochemical calorie per second per square centimetre
The thermochemical calorie per second per square centimetre (cal(th)/(s·cm²)) equals exactly 41840 W/m² (1 cal(th) = 4.184 J; 1 cm² = 10⁻⁴ m²). The CGS unit for very high heat flux: ablation heat flux during atmospheric re-entry ≈ 1-100 cal/(s·cm²). Used in plasma physics and aerospace thermal protection. 1 cal(th)/(s·cm²) = 41840 W/m².
About Celsius Heat Unit per hour per square foot
The Celsius heat unit per hour per square foot (CHU/(h·ft²)) equals (9/5)×1055.05585262/(3600×0.09290304) ≈ 5.6783 W/m². The CHU (= 9/5 BTU(IT)) uses a 1 °C temperature interval instead of 1 °F; historically used in UK and Canadian heating engineering. 1 CHU/(h·ft²) ≈ 5.6783 W/m² = (9/5) × BTU(IT)/(h·ft²).
