About Watt per square millimetre
The watt per square millimetre (W/mm²) equals exactly 10⁶ W/m². Used in high-power laser material processing - cutting, welding, and additive manufacturing - and electron beam applications. A 1 kW laser focused to 1 mm² achieves 1 W/mm². Numerically equal to MW/m². 1 W/mm² = 10⁶ W/m² = 100 W/cm².
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.
