How many horsepower does 1 KW approximately equal?

The relationship between kilowatts (kW) and horsepower (hp) is based on the conversion factors used in electrical and mechanical engineering. Specifically, 1 kilowatt is approximately equal to 1.341 horsepower.

This value is derived from the fact that one horsepower is defined as the ability to do work at a rate of about 0.7457 kilowatts. Therefore, conversely, if you start with 1 kilowatt and convert it to horsepower, you find that it is roughly equivalent to 1.341 hp.

It’s important to recognize that the other values do not align with this conversion. For instance, 1.5 hp represents a higher power output than what 1 kW can provide, and 2 hp significantly exceeds it. The choice of approximately 1.33 aligns most closely with the known conversion factor, making it the best answer among the options provided.
