W/cm²

watt per square centimeter

Intensityexact by definition

The watt per square centimetre is exactly 10000 watts per square metre. It is the working unit of laser material processing, induction and infrared heating, and laser safety analysis above the eye-hazard range, where a continuous beam near 1 W/cm² is already an immediate skin hazard. The conversion is exact.
