1 horsepower equals how many watts?

Explanation:
Understanding how horsepower converts to watts is about translating power units. One horsepower is defined as moving 550 foot-pounds of energy per second. To turn that into watts, use that 1 foot-pound per second equals about 1.3558 watts. Multiply 550 by 1.3558 to get roughly 745.7 watts. When you round to the nearest whole watt, you get 746 watts. That’s why 746 is the best choice here. The other values are just a bit off from the standard rounded figure. (If you ever see metric horsepower, that’s about 735.5 watts, which is a different definition.)
