. say: What horsepower means is this: One horse can do 33,000 foot-pounds of work every minute. So, imagine a horse raising coal out of a coal mine. A horse exerting 1 horsepower can raise 330 pounds of coal 100 feet in a minute, or 33 pounds of coal 1,000 feet in one minute, or 1,000 pounds 33 feet in one minute. You can make up whatever combination of feet and pounds you like. As long as the product is 33,000 foot-pounds in one minute, you have a horsepower.

Mark say: you are exactly right

Steven say: Don't confuse power with force. Power is force times distance per time.

Besides that, automobile horse power is exaggerated by ignoring he (lack of) efficiency.

Maybe it's just me say: Power is the time rate of doing work. Exactly doing 33000 foot pounds of work in one minute is one horsepower. Regarding the car v horse tug of war, it is a curious intellectual discussion that has numerous practicalities to overcome to try it. Horses are animals and not machines. Good luck getting 200 to do anything at just the same time.

Gary B say: Well, that IS how it started.
An engineer, James Watt, became interested in Steam Engines in the late 1800's. He wanted a way to compared the work done by a steam engines to the work done by a team of horse. Therefore, the term HORSEPOWER was invented.
James Watt is primarily famous for investigating the overall cocnept of POWER, and the Unit if Pwer, the "watt", is named after him.
But today, the term HORSEPOWER has be converted to Units Of Power (watts), and one horsepower is about 750 WATTS. In other other words, a Bakers Dozen (13) 60-watt light bulbs would require One Horsepower ti light them./

Markus Imhof say: If a Horsepower would actually be the power of one horse _and_ the horses used the same kind of power tansmission than the car, then you'd be right.
