What does one pound-force inch represent?

It represents the energy done by a one pound-force acting through one inch of displacement, commonly used in US customary mechanical contexts.

How is one horsepower (metric) hour defined?

It is the energy produced by sustaining one metric horsepower for one hour, equivalent to approximately 2,647,795.5 joules.

Why are converted values often very small?

Because pound-force inch is a much smaller unit of energy compared to horsepower (metric) hour, resulting in small numerical conversion results.
