About Nanowatt per square metre
The nanowatt per square metre (nW/m²) equals 10⁻⁹ W/m². Used in astrophysics and cosmology for quantifying extremely weak radiation fields, such as cosmic microwave background intensity and residual thermal emission from near-absolute-zero objects. Relevant in precision cryogenic sensor calibration. 1 nW/m² = 10⁻⁹ W/m² = 10³ pW/m².
About Watt per square centimetre
The watt per square centimetre (W/cm²) equals exactly 10⁴ W/m². A practical unit in laser physics, plasma engineering, and nuclear thermal hydraulics. Nuclear fuel cladding heat flux ≈ 1-5 W/cm²; laser diodes ≈ 10-100 W/cm²; focused CO₂ laser cutting ≈ 10⁴ W/cm². 1 W/cm² = 10⁴ W/m² = 10 kW/m².
