What does one horsepower hour represent?

One horsepower hour is the energy produced by applying one mechanical horsepower continuously for one hour.

Is pound-force foot the same as torque?

While the unit is often used for torque, in this context pound-force foot represents energy from a force applied over a distance.

Why can the conversion involve very large numbers?

Because the horsepower hour is a large energy unit, converting it to pound-force foot results in large numerical values.
