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

It measures heat flux density as the amount of heat transferred per hour across one square foot, specifically one International Table British thermal unit (Btu (IT)) per hour per square foot.

Why convert Btu (IT)/hour/square foot to horsepower/square foot?

Conversion to horsepower/square foot is useful to express heat flux density in terms of mechanical power per unit area, which is common in industrial heat transfer and thermal system design.

Are horsepower per square foot units universally accepted?

No, horsepower per square foot is a non-SI unit and may not be widely accepted in scientific contexts where SI units like W/m² are preferred.
