The foot-pound force (symbol: ft·lbf or ft·lb), sometimes erroneously referred to as feet per pound (symbol: ft/lb), is a unit of work or energy in the Engineering and Gravitational Systems in United States customary and imperial units of measure. It is the energy transferred upon applying a force of one pound-force (lbf) through a linear displacement of one foot. The corresponding SI unit is the joule.

A horsepower-hour (hph) is an outdated unit of energy, not used in the SI system of units. The unit represents an amount of work a horse is supposed capable of delivering during an hour (1 (one) horsepower integrated over a time interval of an hour). Based on differences in the definition of what constitutes the 'power of a horse', a horsepower-hour differs slightly from the German "Pferdestärkenstunde" (PSh):
| 1 horsepower-hours = 1979999.9999999 feet-pound force | 6 horsepower-hours = 11879999.999999 feet-pound force |
| 2 horsepower-hours = 3959999.9999997 feet-pound force | 7 horsepower-hours = 13859999.999999 feet-pound force |
| 3 horsepower-hours = 5939999.9999996 feet-pound force | 8 horsepower-hours = 15839999.999999 feet-pound force |
| 4 horsepower-hours = 7919999.9999995 feet-pound force | 9 horsepower-hours = 17819999.999999 feet-pound force |
| 5 horsepower-hours = 9899999.9999994 feet-pound force | 10 horsepower-hours = 19799999.999999 feet-pound force |
| 1 feet-pound force = 5.0505050505054 × 10-7 horsepower-hours |
| 1 horsepower-hours = 1,979,999.9999999 feet-pound force |
