If 500 watts is consumed, what is its horsepower equivalent?

To convert watts to horsepower, it is essential to know the conversion factor. One horsepower is equivalent to approximately 746 watts. Therefore, to find the horsepower equivalent of 500 watts, you can use the formula:

Horsepower (HP) = Watts / 746

By performing the calculation:

HP = 500 watts / 746 watts/HP

HP ≈ 0.67

This implies that 500 watts is approximately 0.67 horsepower, which aligns with the first choice. This conversion is fundamental in understanding power units, particularly in comparing electrical power with mechanical power outputs. The other options represent higher horsepower values that exceed the conversion derived from 500 watts, making them unattainable given the established relationship between watts and horsepower.
