A horsepower-hour (hph) is an outdated unit of energy, not used in the SI system of units.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 = 23759999.999998 inch-pounds force | 6 horsepower-hours = 142559999.99999 inch-pounds force |
| 2 horsepower-hours = 47519999.999997 inch-pounds force | 7 horsepower-hours = 166319999.99999 inch-pounds force |
| 3 horsepower-hours = 71279999.999995 inch-pounds force | 8 horsepower-hours = 190079999.99999 inch-pounds force |
| 4 horsepower-hours = 95039999.999994 inch-pounds force | 9 horsepower-hours = 213839999.99999 inch-pounds force |
| 5 horsepower-hours = 118799999.99999 inch-pounds force | 10 horsepower-hours = 237599999.99998 inch-pounds force |
A inch-pound force is a unit of engery.
