I m under the impression, that let s say that a car has 200 hp. Does this mean that if it had a tugofwar with 200 horses, it would be a stale mate?

answers:
Fazaldin A say: car has 200 hp. It Does not mean that it had a power of 200 horses,
Technically, 1horsepower = 745.7 Nm/sec = 746 Watts.
So,
Car has 200 hp = 746 x 200 = 149200 Nm/sec.

say: The term came from James Watt studying one horse doing work, that walked in circles and pumped water.
He observed it, and decided the horse could lift 33,000 lbs. of water a height of 1 foot in 1 minute.
Yes, 1 hp. was born. Its definition has changed over the years, however.

J say: The term is based upon the daily output of horses, not upon their pulling strength.
Everybody else is wrong.

say: Power.

Philomel say: 1 HP is defined as 550 Ft Lbs/ sec.
If you raise a weight of 550 lbs at a rate of 1 ft/ sec that is 1 HP
If you raise a weight of 1 lb at a rate of 550 ft/ sec That is 1 HP.
If " " 225 lb " 2 ft/sec 1HP.
etc.
This is approximately what a standard work horse can do in work.

https://en.wikipedia.org/wiki/Horsepower
THE CAR HAS 200HP DOES NOT MEAN IT IS EQUAL TO THE WHOLE FORCE PULLING BY 200 HORSES. GASOLINE CAR HAS NOT MORE THAN 35% TO 40% EFFICENCY. 200HP CAR ENGINE IS A RATE TO BE USED TO ESTIMATE HOW ITS POWER COMPARE TO OTHER TYPE ENGINE.

Samwise say: No, but that would be super sweet to see.

BOSFLASH say: Here's the derivation:
The derivation of horsepower. The term horsepower was coined in the late 18th century when James Watts was looking for a way to convince brewery owners to replace horses with steam engines. ... Therefore one horsepower is equal to 150 x220/1 or 33,000 foot pounds per minute or 745.699872 watts.
