A horsepower-hour (hph) is an outdated unit of energy, not used in the SI system of units.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 = 5827.8978016403 gallons-atmosphere (imperial) | 6 horsepower-hours = 34967.386809842 gallons-atmosphere (imperial) |
| 2 horsepower-hours = 11655.795603281 gallons-atmosphere (imperial) | 7 horsepower-hours = 40795.284611482 gallons-atmosphere (imperial) |
| 3 horsepower-hours = 17483.693404921 gallons-atmosphere (imperial) | 8 horsepower-hours = 46623.182413122 gallons-atmosphere (imperial) |
| 4 horsepower-hours = 23311.591206561 gallons-atmosphere (imperial) | 9 horsepower-hours = 52451.080214763 gallons-atmosphere (imperial) |
| 5 horsepower-hours = 29139.489008202 gallons-atmosphere (imperial) | 10 horsepower-hours = 58278.978016403 gallons-atmosphere (imperial) |
The gallon-atmosphere (imperial) is the unit of Energy.
| 1 gallons-atmosphere (imperial) = 0.00017158845848644 horsepower-hours | 6 gallons-atmosphere (imperial) = 0.0010295307509187 horsepower-hours |
| 2 gallons-atmosphere (imperial) = 0.00034317691697289 horsepower-hours | 7 gallons-atmosphere (imperial) = 0.0012011192094051 horsepower-hours |
| 3 gallons-atmosphere (imperial) = 0.00051476537545933 horsepower-hours | 8 gallons-atmosphere (imperial) = 0.0013727076678916 horsepower-hours |
| 4 gallons-atmosphere (imperial) = 0.00068635383394578 horsepower-hours | 9 gallons-atmosphere (imperial) = 0.001544296126378 horsepower-hours |
| 5 gallons-atmosphere (imperial) = 0.00085794229243222 horsepower-hours | 10 gallons-atmosphere (imperial) = 0.0017158845848644 horsepower-hours |
| 1 horsepower-hours = 5,827.8978016 gallons-atmosphere (imperial) |
| 1 gallons-atmosphere (imperial) = 0.0001716 horsepower-hours |
