Conversion Formula
µW/m² = W/mm² × 1000000000000
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 Microwatt per square metre
The microwatt per square metre (µW/m²) equals 10⁻⁶ W/m². Encountered in geothermal science - deep crustal heat flux measurements in stable shield regions can reach a few µW/m² - and in bio-electromagnetic research for very low intensity radiation fields. 1 µW/m² = 10⁻⁶ W/m² = 10³ nW/m².
