**Horsepower (550ft-Lbf/s)-Hour**

**Horsepower (550ft-Lbf/s)-Hour (Hp-h)**is a unit in the category of

*Energy*. It is also known as horsepower-hour, horsepower hour. This unit is commonly used in the US unit system. Horsepower (550ft-Lbf/s)-Hour (Hp-h) has a dimension of ML

^{2}T

^{-2}where M is mass, L is length, and T is time. It can be converted to the corresponding standard SI unit J by multiplying its value by a factor of 2684519.5374.
