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 Watt per square inch
The watt per square inch (W/in²) equals 1/(6.4516×10⁻⁴) ≈ 1550.003 W/m² (1 in = 0.0254 m). Used in US electronics thermal management for PCB power density, semiconductor die heat flux, and power module ratings. 1 W/in² ≈ 1550 W/m² ≈ 0.155 W/cm².
