For the last century, horsepower has been used to describe the power output of the internal combustion engine. The horsepower unit was created by James Watt in the 18th century. Its origin is based from how much power a horse could lift in foot pounds, 33,000 ft-lbs to be exact in one minute. The unit is derived from torque, which is the true measurement of the engine physical power production.
What is strange about the units of horsepower is that it has no physical meaning. Its an arbitrary unit that has no real signficance in describing the characterisitc of the engine. For those that are curious to calculate horsepower:
Horsepower=(rpm/5252)*torque.... (Click Link below for continuation!!)
