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 International table BTU per hour per square inch
The international table BTU per hour per square inch (BTU(IT)/(h·in²)) equals 1055.05585262/(3600×6.4516×10⁻⁴) ≈ 454.26 W/m². Used for high heat flux applications such as electronic component cooling, jet engine combustor walls, and nuclear fuel assembly design in US customary units. 1 BTU(IT)/(h·in²) ≈ 454.26 W/m².
