Horsepower (hp) is a unit of measurement of power (the rate at which work is done).
It is that arbitrary unit of measure that has made its way down through the centuries and now appears on your car, your lawn mower, your chain saw and even in some cases your vacuum cleaner. What horsepower means is this: In Watt's judgement, one horse can do 33,000 foot-pounds of work every minute.
