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

It is an imperial power unit equal to 550 foot-pound-force per second, historically defined by James Watt, often used to rate small engines and motors.

Why convert horsepower to foot pound-force/hour?

This conversion expresses large power ratings into smaller, detailed units suited for legacy machinery or precise engineering contexts involving imperial units.

Can I use this conversion for modern engineering designs?

While possible, foot pound-force/hour is a non-SI unit mainly relevant for legacy systems or historical equipment, with modern designs typically using SI units.
