What does watt per square inch measure?

Watt per square inch measures heat flux density, indicating power transferred or incident per unit area of one square inch.

Why convert watt/square inch to watt/square centimeter?

Converting to watt/square centimeter expresses heat flux in metric units, facilitating scientific, engineering, or regulatory work where metric units are standard.

Does converting units change the physical quantity?

No, conversion changes only the unit expression, not the actual physical heat flux density value.
