What is horsepower (550 ft*lbf/s)?

It is an imperial power unit equal to 550 foot-pound-force per second, measuring the rate of doing mechanical work or energy transfer.

What does Btu (IT)/second represent?

It is a unit of power representing one International Table British thermal unit of energy transferred per second, often used in heat transfer and energy conversion contexts.

When should I convert horsepower to Btu (IT)/second?

When you need to relate mechanical power ratings in imperial units to thermal power output or heat transfer rates for engineering, HVAC, or industrial heating purposes.
