What does horsepower (550 ft*lbf/s) measure?

Horsepower (550 ft*lbf/s) is an imperial unit of mechanical power, defined as 550 foot-pound-force per second, used to quantify the rate of doing work or energy transfer.

Where is Btu (IT)/minute commonly used?

Btu (IT)/minute is used to quantify thermal power, especially in HVAC, refrigeration, and industrial heating applications.

Can I directly convert mechanical horsepower to thermal power in all scenarios?

Direct conversion is meaningful when mechanical power ratings relate to thermal energy processes, but it may not be appropriate in all contexts due to differences between mechanical and thermal power units.
