Does one horsepower equal one horse? Not quite. It’s a common misconception that one horsepower is equal to the peak power production of a horse, which is capable of a maximum of around 14.9 horsepower. By comparison, a human being is capable of approximately five horsepower at peak power production.
How is horsepower calculated?
Multiply the torque by the engine speed.
You will be using the formula (RPM * T) / 5252=HP, where RPM is the engine speed, T is the torque, and 5,252 is radians per second. The first calculation you want to do is multiply the torque and the engine speed. For example, a Porsche generates 480 of torque at 2,500RPM.
Why is it called horsepower?

Why are horses so powerful?
Horses are as strong as they need to be for such a large animal, but most of their strength is related to speed. To avoid being eaten, they need to react quickly and attain their maximum speed as quickly as possible, so they need large enough muscles to take off in a sprint.
