# How much HP has a horse?

PLS.calculate

Horsepower from a horse:

R. D. Stevenson and R. J. Wasserzug published an article in Nature 364, 195-195 (15 July 1993) calculating the upper limit to an animal's power output. The peak power over a few seconds has been measured to be as high as 14.9 hp. However, for longer periods an average horse produces less than one horsepower.

The term "horsepower" was created by the engineer James Watt in 1782. Watt (1736 to 1819) is most famous for his work on improving the performance of steam engines.

Watt was working with ponies lifting coal at a coal mine, and he wanted to define the power available from one of these animals. He found that, on average, a mine pony could do 22,000 foot-pounds (lift a bucket of coal weighing 22,000 lb. a distance of 1-foot) of work in a minute. Watt then judged a horse was 50% more powerful than a pony and thus arrived at the 33,000 ft·lbf/min figure.

Under this system, one horsepower is defined as:

1 hp = 33,000 ft·pound-force·min−1 = 746 W
one
one!
That would be the power of one horse then. =1HP
It depend on horse.. Healthier one may get one HP..

About 0.001 % of a Bugatti
1 horsepower = 745.699872 watts
.... and that equals to one horse

Horsepower is defined as work done over time. The exact definition of one horsepower is 33,000 lb.ft./minute. Put another way, if you were to lift 33,000 pounds one foot over a period of one minute, you would have been working at the rate of one horsepower. In this case, you'd have expended one horsepower-minute of energy.
one .. unless you mean to give it credit for more
In fact 2/3 HP when James Watt calculated HP he measured a horse lifting a weight up a coalmine shaft and recorded 22000fpm. after several times he thought the horse was capable of much more and gave the figure as 33000fpm. this has been the national unit ever since 746 electric watts
1... hence (horse power) =)
A horse must mean one horse therefore one horse power (1HP)
A carthorse, one or those big ones, can deliver approximately three-quarters of a horsepower (at the road surface).

I don't know where the original measurement came from, but you could calculate the horsepower of any horse if you had some data.

power=forceXspeed :-

So you could gallop a horse up a known slope and record the time it took to get up it, and then calculate its Horesepower (from the angle of the slope, the length of the slope, the weight of the horse plus any rider, and the time it took to get up the slope).

Alternatively pulling against known force such as a loaded cart, and measuring the maximum speed it could achieve (you would need to measure the force between horse and cart, and the horse's maximum speed) and from that data you could calculate its Horsepower.

It's not dificult to calculate for any horse, but you do need actual data to put into your calculation.
in terms of energy i horse power equals 746 watts

Stuck a Turbo on it, and u will have a 25% increase, but i wouldn't stand behind it for the fear of getting poo'ed on...
Electrically! 746watts.
The formula for one horsepower was a 19th century approximation, in fact a horse produces nowhere near one horsepower.
An average sized horse has been worked out to produce around 0.4 horsepower, 0.75 for a carthorse sounds about right given their size and heavier build.
Err let's see 2+14.5 /6.27 = .22...lots.
