What does 1 Btu (th)/minute/square foot represent?

It represents the heat flux density corresponding to one British thermal unit of thermal energy transferred per minute across one square foot of surface area.

Why convert to horsepower per square foot?

Converting to horsepower per square foot expresses heat flux in terms of mechanical power delivered or removed per unit area, which is useful in industrial and thermal system power evaluations.

Can this conversion be used for all heat flux measurements?

This conversion is specific to non-SI units and is best applied in HVAC, combustion equipment rating, and thermal system design contexts rather than all heat flux scenarios.
