About International table kilocalorie per hour per square metre
The international table kilocalorie per hour per square metre (kcal(IT)/(h·m²)) equals 4186.8/3600 ≈ 1.1633 W/m² (1 kcal(IT) = 4186.8 J; 1 h = 3600 s). The IT variant used in steam engineering, solar thermal collector standards, and process heat calculations. 1 kcal(IT)/(h·m²) ≈ 1.1633 W/m².
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.
