According to that story, he have the need of a unit to measure the force from one of this animals. He founds that they can move 22.000 lbs per minute, so he (arbitrarily) increase this measure in 50% been the unit Horsepower in 33.000 lb/feet per minute.

    Explanation:

    This measure unit can measure "work" or "force". In the SI correspond to move up 75 Kg, to 1 meter high, in one second.

    1 HP = (330 lb) x (100 feet) / 1min = 33000 lb x feet/min

    Why would anyone wish to express power in HP?

    Is a practical unit, because reduce the amount of digits in a specific value. Also, his use is very spread specially in mechanical applications.

    1 HP = 746 W (0,746 kW).
