About Watt per Square Centimeter (W/cm²)
A heat-flux unit equal to 10,000 W/m² — used where heat-flux values are very high: laser processing (cutting/welding), power-electronics cooling (CPUs dissipate 10–100 W/cm² at the die), plasma arc surfaces, and thermal weapons analysis. Semiconductor thermal datasheets routinely specify maximum die heat flux in W/cm².
About BTU per Hour-Square Foot (BTU/(hr·ft²))
An imperial heat-flux unit used in US HVAC, building-envelope analysis, and heat-exchanger design. ASHRAE design loads, solar heat-gain tables for windows, and HVAC equipment ratings commonly use BTU/(hr·ft²). Common peak solar heat gain through a south-facing window might be 200–300 BTU/(hr·ft²). 1 BTU/(hr·ft²) ≈ 3.155 W/m².
