μW/m²
microwatt per square meter
Intensityexact by definition
The microwatt per square metre is one millionth of a watt per square metre. It is used for weak radiofrequency exposure levels, faint optical signals and low-level acoustic intensity, where the threshold of human hearing at 1 kHz corresponds to about one picowatt per square metre. The factor of 1e-6 is exact, being an SI prefix.
