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

It is an imperial unit of power equal to the mechanical work rate of 550 foot-pound-force per second, commonly used for engine ratings.

What is calorie (IT)/second used for?

It quantifies thermal power by measuring the transfer rate of one International Table calorie per second, mainly in heat-transfer contexts.

Can I use this conversion for all power calculations?

This conversion applies when comparing mechanical power to thermal power but does not account for conversion inefficiencies or losses.
