Question

One kilowatt is approximately equal to:

• A. 1.34 hp
• B. 1.56 hp
• C. 2.50 hp
• D. 1.83 hp

Answer 1

Answer: (A)

1.34 hp

A kilowatt equals to one thousand watts or one thousand joules per second.

The horsepower (hp) is a unit in the foot-pound-second ( fps ) or English system, sometimes used to express the rate at which mechanical energy is expended. It was originally defined as 550 foot-pounds per second. A power level of 1 hp is approximately equivalent to 746 watt s (W) or 0.746-kilowatt s (kW).

So $1kW=\frac{1}{0.746}=1.34hp$
