Horsepower-hour ( unit symbol : hph ) is a unit of energy that is not permitted in the SI . She describes pictorially speaking, the work , which is capable of accomplishing a horse in one hour (the performance of a horse over the time period of one hour integrated ). Because of certain differences in the definition of a horsepower , the true horsepower-hour not exactly with the previously used in German-speaking horsepower hour (abbreviated PSh) match.
1 hph = 1.014 PSh = 0.7457 kWh
