A horsepower-hour (hph) is an outdated unit of energy, not used in the SI system of units.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 = 6999.0134307298 gallons-atmosphere (US) | 6 horsepower-hours = 41994.080584379 gallons-atmosphere (US) |
| 2 horsepower-hours = 13998.02686146 gallons-atmosphere (US) | 7 horsepower-hours = 48993.094015109 gallons-atmosphere (US) |
| 3 horsepower-hours = 20997.040292189 gallons-atmosphere (US) | 8 horsepower-hours = 55992.107445839 gallons-atmosphere (US) |
| 4 horsepower-hours = 27996.053722919 gallons-atmosphere (US) | 9 horsepower-hours = 62991.120876568 gallons-atmosphere (US) |
| 5 horsepower-hours = 34995.067153649 gallons-atmosphere (US) | 10 horsepower-hours = 69990.134307298 gallons-atmosphere (US) |
| 1 gallons-atmosphere (US) = 0.0001429 horsepower-hours |
| 1 horsepower-hours = 6,999.0134307 gallons-atmosphere (US) |
