A horsepower-hour (hph) is an outdated unit of energy, not used in the SI system of units.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 = 2684519.537696 joules | 6 horsepower-hours = 16107117.226176 joules |
| 2 horsepower-hours = 5369039.075392 joules | 7 horsepower-hours = 18791636.763872 joules |
| 3 horsepower-hours = 8053558.613088 joules | 8 horsepower-hours = 21476156.301568 joules |
| 4 horsepower-hours = 10738078.150784 joules | 9 horsepower-hours = 24160675.839264 joules |
| 5 horsepower-hours = 13422597.68848 joules | 10 horsepower-hours = 26845195.37696 joules |
The joule (/ˈdʒuːl/); symbol: J), is a derived unit of energy in the International System of Units. It is equal to the energy transferred to (or work done on) an object when a force of one newton acts on that object in the direction of its motion through a distance of one metre (1 newton metre or N⋅m).
