What does watt per square centimeter represent?

It indicates the rate of energy transfer in watts per each square centimeter of surface area, used to quantify localized power in heat flux measurements.

Why convert watt/cm² to CHU/hr/ft²?

Conversion enables using laser or scientific heat flux data in HVAC and building thermal energy contexts measured per square foot.

Are conversions always accurate between these units?

Accuracy depends on the local definition of one CHU and assumes steady, uniform heat flux conditions.
