A horsepower-hour (hph) is an outdated unit of energy, not used in the SI system of units.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) |
The gallon-atmosphere (US) is the unit of Energy.
| 1 gallons-atmosphere (US) = 0.00014287727976195 horsepower-hours | 6 gallons-atmosphere (US) = 0.00085726367857167 horsepower-hours |
| 2 gallons-atmosphere (US) = 0.00028575455952389 horsepower-hours | 7 gallons-atmosphere (US) = 0.0010001409583336 horsepower-hours |
| 3 gallons-atmosphere (US) = 0.00042863183928584 horsepower-hours | 8 gallons-atmosphere (US) = 0.0011430182380956 horsepower-hours |
| 4 gallons-atmosphere (US) = 0.00057150911904778 horsepower-hours | 9 gallons-atmosphere (US) = 0.0012858955178575 horsepower-hours |
| 5 gallons-atmosphere (US) = 0.00071438639880973 horsepower-hours | 10 gallons-atmosphere (US) = 0.0014287727976195 horsepower-hours |
| 1 horsepower-hours = 6,999.0134307 gallons-atmosphere (US) |
| 1 gallons-atmosphere (US) = 0.0001429 horsepower-hours |
