How many horsepower is approximately equal to 1 KW?

The conversion between kilowatts (KW) and horsepower (HP) is an important aspect in understanding power measurements. One kilowatt is approximately equal to 1.341 horsepower. Therefore, when rounded to a simpler fraction, 1 kilowatt can be represented as about one and one-third horsepower.

Thus, the choice that indicates one and one-third accurately reflects this conversion ratio. While other options may suggest different horsepower values, they do not align with the established conversion metric for kilowatts to horsepower. This makes the selected choice the most appropriate answer based on the available data.
