Convert Watt per square millimetre to Watt per square centimetre
Convert Watt per square millimetre (W/mm²) to Watt per square centimetre (W/cm²) instantly and accurately.
Conversion Formula
W/cm² = W/mm² × 100
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 Watt per square centimetre
The watt per square centimetre (W/cm²) equals exactly 10⁴ W/m². A practical unit in laser physics, plasma engineering, and nuclear thermal hydraulics. Nuclear fuel cladding heat flux ≈ 1-5 W/cm²; laser diodes ≈ 10-100 W/cm²; focused CO₂ laser cutting ≈ 10⁴ W/cm². 1 W/cm² = 10⁴ W/m² = 10 kW/m².
