What does Btu (IT)/hour measure?

Btu (IT)/hour is a unit of power representing the rate of heat transfer, specifically one International Table British thermal unit transferred per hour.

Why convert Btu (IT)/hour to horsepower (550 ft·lbf/s)?

Converting allows comparing thermal power rates with mechanical power units, useful for engineering and equipment specification across different measurement systems.

Can this conversion be used for any type of power comparison?

Primarily, it is intended when thermal power is related or needs translating to mechanical power, considering their different physical meanings.
