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 Watt per square inch
The watt per square inch (W/in²) equals 1/(6.4516×10⁻⁴) ≈ 1550.003 W/m² (1 in = 0.0254 m). Used in US electronics thermal management for PCB power density, semiconductor die heat flux, and power module ratings. 1 W/in² ≈ 1550 W/m² ≈ 0.155 W/cm².
