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.
About Milliwatt per square metre
The milliwatt per square metre (mW/m²) equals 10⁻³ W/m². Relevant in geothermal surveys: global average continental heat flux ≈ 65 mW/m², oceanic ≈ 101 mW/m². Used in building physics for quantifying very small heat leakage through ultra-high-performance insulation. 1 mW/m² = 10⁻³ W/m² = 1 erg/(s·cm²).
