What is one horsepower equal to?

Answer 1

The term horsepower was invented by the engineer James Watt. Watt was working with ponies lifting coal at a coal mine, and he wanted a way to talk about the power available from one of these animals. He found that, on average, a mine pony could do 22,000 foot-pounds of work in a minute. He then increased that number by 50 percent and pegged the measurement of horsepower at 33,000 foot-pounds of work in one minute. So, 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.

Answer 2

A horse actually is stronger than one horse power: 14.9hp is the amount of power an ACTUAL horse produces, but over longer periods of time, the average horse produces less than one hp.

But The horsepower is the amount a horse can produce for a continuous time period at a slow haul, however in a gallop for short periods that power level shoots up dramatically, this is why a horse can whip say a 5hp mini motorbike.

Answer 3

One horsepower is equal to the power needed to lift 550 pounds one foot in one second, or 746 watts.

Answer 4

So far, on the internet, I have read a) 22 lbs. of thrust = 1 hp. b) 12 lbs. of thrust = 1 hp.

Answer 5

1 horsepower equals 745.69987 watts. Scroll down to related links and look at "Electrical Power" and "Energy".

Answer 6

1 HP = 746 watts.

1 hp (metric) = 735.499W 1 hp (US = 550ft-lbf/s) = 745.7W

Answer 7

from memory at trade school , it is 743 watts = 1 horse powercheers

Answer 8

22.5 horsepower

Answer 9

746 joules
