What is a horsepower hour (hp*h)?

A horsepower hour is a unit of energy representing one horsepower sustained for one hour, typically based on mechanical horsepower.

What does one foot-pound represent?

One foot-pound is the energy from a one pound-force moving an object one foot in the force direction, used to measure small mechanical energy amounts.

Why convert horsepower hour to foot-pound?

Converting hp*h to foot-pound helps express mechanical work in a smaller imperial unit suitable for torque and impact energy calculations.
