How much horsepower does a horse have? Watt's estimates were fairly accurate: one horsepower is roughly the average rate of work a healthy draught horse can do over a full day, confirmed by data from the 1925 Iowa State Fair and by English veterinary surgeon William Youatt. In 1993, biolog...
The term horsepower was invented by the engineer James Watt. Watt lived from 1736 to 1819 and is most famous for his work on improving the power output of steam engines. We are also reminded of him every day when we talk about 60-watt light bulbs. How Much Horsepower Does a Horse Have...
Watt calculated that one horsepower could lift 550 lbs (250 kg) of weight by 1 ft (300 mm) in 1 second.But how much “horsepower” does a horse really make. Insane as it sounds, Donut Media hooked one up to a dyno to find out once and for all. Hooves and rollers tend not t...
Just about every car ad on TV mentions it, people talking about their cars bandy the word about and even most lawn mowers have a big sticker on them to tell you how much horsepower the engine has. But what is horsepower, and how much horsepower does a horse have? What does the horsepo...

For about as long as cars have been around, the thing to say when a powerful car rolls by has been: "How much horsepower are you running?" But now that we're moving to an age of electric vehicles, that may change to "How many kilowatts does that baby have?" ...
Siemens' modern engines produce up to 4,200 horsepower, and the generator can turn this into almost 4,700 amps of electrical current. The drive motors use this electricity to generate around 60,000 lb-ft of torque. There is also a secondary diesel engine and generator to provide electrical ...
