What does horsepower per square foot measure?

Horsepower per square foot measures power delivered or removed per unit area, representing mechanical power density on a surface.

Why convert from hp/ft² to Btu (IT)/s/ft²?

Converting to Btu (IT)/second/square foot facilitates interpretation and standardization in thermal sciences, fire testing, and furnace specification contexts.

Are these units part of the SI system?

No, both horsepower per square foot and Btu (IT)/second/square foot are non-SI units commonly used in specific thermal measurement applications.
