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 kilocalorie per hour per square centimetre
The thermochemical kilocalorie per hour per square centimetre (kcal(th)/(h·cm²)) equals 4184/(3600×10⁻⁴) ≈ 11622 W/m² (= 10⁴ × kcal(th)/(h·m²)). A high-flux variant of the metric heat flux unit found in older combustion engineering and furnace design references. 1 kcal(th)/(h·cm²) ≈ 11622 W/m².
