What does Btu (IT)/second/square foot measure?

It measures heat flux density as the energy transferred in British thermal units (International Table) per second across one square foot of surface area.

Why convert to horsepower (metric)/square foot?

This unit is used to express heat transfer rates when power is given in metric horsepower while area is in square feet, commonly needed in industrial applications.

Can this converter be used for transient heat flux?

No, the conversion assumes steady-state or quasi-steady heat flux conditions, so transient cases may not be accurately represented.
