Convert Watt per square millimetre to Milliwatt per square centimetre
Convert Watt per square millimetre (W/mm²) to Milliwatt per square centimetre (mW/cm²) instantly and accurately.
Conversion Formula
mW/cm² = W/mm² × 100000
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 Milliwatt per square centimetre
The milliwatt per square centimetre (mW/cm²) equals exactly 10 W/m² (1 mW = 10⁻³ W; 1 cm² = 10⁻⁴ m²). Widely used in photonics, laser safety standards (IEC 60825), and UV dosimetry. Solar irradiance at Earth's surface ≈ 100 mW/cm². 1 mW/cm² = 10 W/m² = 0.001 W/cm².
