About Watt per square metre
The watt per square metre (W/m²) is the SI coherent unit for heat flux density and irradiance. Solar irradiance at Earth's surface ≈ 1000 W/m²; solar constant ≈ 1361 W/m²; human skin radiative emission ≈ 100 W/m²; global average geothermal flux ≈ 0.087 W/m². Referenced in ISO 80000-4. 1 W/m² = 1 J/(s·m²) = 10⁻³ kW/m².
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.
