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

It is an imperial unit of power equal to 550 foot-pound-force per second, measuring the rate of doing work or transferring energy.

In what situations is calorie (th)/hour used?

It measures thermal power for small heat transfer rates in laboratory calorimetry, metabolic heat production, and thermal component heat-loss assessments.

Why might the converted values be very large?

Because the conversion factor from horsepower to calorie (th)/hour is large, small mechanical power inputs result in high numerical heat transfer values.
