What is horsepower (hp) used for?

Horsepower is a non-SI unit of power commonly used to rate engine output, specify motor power, and compare performance in mechanical applications.

What does kilocalorie (th)/hour measure?

Kilocalorie (th)/hour measures the rate of heat flow, representing one thermochemical kilocalorie transferred every hour.

Why might I need to convert horsepower to kilocalorie (th)/hour?

This conversion is useful when comparing mechanical power to thermal energy transfer or when technical specifications require units of heat flow.
