Horsepower (hp) is a unit of measurement of power (the rate at which work is done).
And because one of Watt's horses says that's the way it ought to be, one horsepower is equal to the amount of power it takes to perform 33,000 ft-lb of work in a single minute. In other words, one horsepower is equal to the amount of energy required to lift 550 pounds one foot in one second.
