Work is the product of the force applied and the distance the object moves in the direction of that force, reflecting how much energy is transferred. In US customary units, that amount of work is measured in foot-pounds. For example, applying 10 pounds of force over a distance of 2 feet results in 20 foot-pounds of work. Horsepower is a rate (work per unit time), time is a duration, and weight is a force, not a measure of work. So the unit that fits the concept here is foot-pounds.
