Explanation
horsepower and BTU per hour are units of power. They are used in common measurement contexts. Which one you use depends on the unit system or industry. They are defined at different scales, so the factor is not 1: 1 horsepower = 2544.4335791393 BTU per hour, and 1 BTU per hour = 0.0003930148 horsepower. Because one BTU per hour represents a smaller amount than one horsepower, the numeric value gets larger in this direction.
