How many watts are equivalent to one horsepower?

Explanation:
Power is the rate at which work is done, and one horsepower is defined as 550 foot-pounds of work per second. Converting that to watts uses that 1 foot-pound is about 1.356 joules, so 550 × 1.356 ≈ 745.8 joules per second, i.e., watts. That makes one horsepower roughly 746 watts. The other options don’t fit because they correspond to significantly different power levels: 500 W is about 0.67 hp, 1000 W is about 1.34 hp, and 2000 W is about 2.68 hp.
