A horsepower-hour (hph) is an outdated unit of energy, not used in the SI system of units.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 = 0.002684519537696 gigajoules | 6 horsepower-hours = 0.016107117226176 gigajoules |
| 2 horsepower-hours = 0.005369039075392 gigajoules | 7 horsepower-hours = 0.018791636763872 gigajoules |
| 3 horsepower-hours = 0.008053558613088 gigajoules | 8 horsepower-hours = 0.021476156301568 gigajoules |
| 4 horsepower-hours = 0.010738078150784 gigajoules | 9 horsepower-hours = 0.024160675839264 gigajoules |
| 5 horsepower-hours = 0.01342259768848 gigajoules | 10 horsepower-hours = 0.02684519537696 gigajoules |
The gigajoule (GJ) is equal to one billion (109) joules. 6 GJ is about the chemical energy of combusting 1 barrel (160 l) of crude oil. 2 GJ is about the Planck energy unit.
