Horsepower vs Torque

Horsepower vs Torque
 
Many individuals read and hear about horsepower and torque all the time, but don’t understand what it really means. Read along to find out the difference between the two, and how they relate to each other in automobiles.
 
Torque is the amount of force required to turn a screw. It’s calculated by the number of pounds required (or the power) needed to turn a one foot wrench.
 
Horsepower was created many years ago by James Watt when he determined how much work, in foot-pounds a horse could achieve in a minute. 1 horsepower is the same as a horse moving a 330 lb load 100 feet in a minute. Therefore, 1 hp = 33 foot pounds.
 
Torque and horsepower go together as one if the force needed to move a load around a fixed point while the other is the force needed to move a load over a distance. Using a series of conversions, 1 hp is equal to 5252 rpm. Maximum torque always occurs at a value under 5252 rpm while maximum horsepower occurs at a value above 5252 rpm.
