What is the exact conversion factor from horsepower to kilocalorie (th)/second?

The conversion factor is 1 horsepower (hp, hp UK) equals 0.1782265467 kilocalorie (th)/second.

Where is kilocalorie (th)/second commonly used?

It is mainly used in thermal engineering fields, such as HVAC design, calorimetry, and heat exchanger sizing, where heat flow rates are expressed in calorie-based units.

Why is it important to know the horsepower variant when converting?

Because different definitions of horsepower exist, such as mechanical and metric, and using the wrong variant can lead to inaccurate conversions.
