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

It is an imperial power unit used to rate internal-combustion engines, small engines like lawnmowers, and to size pumps and motors in imperial unit contexts.

When should I use calorie (IT)/hour as a power unit?

Calorie (IT)/hour is used for expressing very small steady heat flow rates, such as in laboratory calorimetry or thermal testing of materials.

Is this conversion relevant for general mechanical power calculations?

No, the conversion is primarily relevant in specialized thermal and calorimetric contexts rather than common mechanical power applications.
