A horsepower-hour (hph) is an outdated unit of energy, not used in the SI system of units.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 = 63704616.141728 feet-poundal | 6 horsepower-hours = 382227696.85037 feet-poundal |
| 2 horsepower-hours = 127409232.28346 feet-poundal | 7 horsepower-hours = 445932312.9921 feet-poundal |
| 3 horsepower-hours = 191113848.42518 feet-poundal | 8 horsepower-hours = 509636929.13383 feet-poundal |
| 4 horsepower-hours = 254818464.56691 feet-poundal | 9 horsepower-hours = 573341545.27555 feet-poundal |
| 5 horsepower-hours = 318523080.70864 feet-poundal | 10 horsepower-hours = 637046161.41728 feet-poundal |
The foot-poundal (symbol: ft-pdl) is a unit of energy that is part of the foot-pound-second system of units, in Imperial units introduced in 1879, and is from the specialized subsystem of English Absolut (a coherent system). The foot-poundal is equal to 1/32.174049 that of the more commonly used foot-pound force.

| 1 feet-poundal = 1.5697449581601 × 10-8 horsepower-hours |
