What is Horsepower?

The horsepower of a motor indicates how much work the motor can perform. The horsepower is the measure of how much power it can produce over a period of time. Horsepower is indicated as hp.

1 hp = 746 watts or 0.746 kW (as per IEC standard 60072-1)

The term is usually used when referring to engines for cars and other motorized vehicles.

However, the output of the pumps used in industries is often measured in horsepower (hp).

How to convert horsepower (hp) to kilowatts (kW)?

We know the equation that,

1 hp = 746 watts or 0.746 kW

So, to convert horsepower into kilowatts just multiply kilowatts (kW) value into 1.34.

Example: Let us say you have 7.5 kW motor. The calculated horsepower of AC motor is 10.050 hp.

How to convert kilowatts (kW) to horsepower (hp)?

As per the equation,

1 hp = 746 watts or 0.746 kW

So, to convert kilowatts into horsepower just multiply horsepower (hp) value into 0.746.

Example: Let us say you have 5 hp motor. The calculated kilowatts of AC motor is 3.7 kW.
