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

It is an imperial power unit equal to 550 foot-pound-force per second, representing mechanical power output as defined by James Watt.

Why convert horsepower to kilocalorie (IT)/second?

Converting allows comparison and analysis between mechanical power and thermal energy transfer rates, useful in fields like engineering and biomedical research.

Is the kilocalorie (IT)/second commonly used today?

It is less common in modern SI systems, which typically prefer watts, but it remains useful in certain thermal and metabolic energy contexts.
