The term horsepower was adopted by Scottish inventor James Watt to measure the power output of his steam engine and to compare that power with that of horses.

There are now several different types of horsepower, including mechanical, electrical, metric, boiler, brake, and indicated, and they all have different applications in industry. Mechanical and electric are the most commonly used types.

## What is Horsepower?

A unit that is used to measure the power of engines and motors. One unit of horsepower is equal to the power needed to lift 550 pounds one foot in one second. This unit has been widely replaced by the watt in scientific usage; one horsepower is equal to 745.7 watts.

## What is Kilowatt?

A kilowatt is measuring unit of electric power in SI unit. kilowatt symbol is “kW”. A kilowatt is 1000 watts of electric current. A watt of electric current is measured in power. One kilowatt is equal to 1.3596216173 horsepower (metric).

## How to convert horsepower to kilowatts?

different horsepower units can be converted to kilowatts in different ways. Following are the ways to convert horsepower to kilowatts.

### Mechanic / Hydraulic horsepower to kilowatts

One mechanic or hydraulic horsepower is equal to 0.745699872 kilowatts:

**1 hp(I) = 745.699872 W = 0.745699872 kW**

Therefore, the power conversion of horsepower to kilowatts will be given by;

**P(kW) = 0.745699872 ⋅ P(hp)**

**Example: Convert 10 hp to kW:**

P(kW) = 0.745699872 ⋅ 10hp = 7.45699872 kW

### Electrical horsepower to kilowatts

One electrical horsepower is equal to 0.746 kilowatts:

1 hp(E) = 746 W = 0.746 kW

So the power conversion of horsepower to kilowatts is given by:

**P(kW) = 0.746 ⋅ P(hp)**

**Example: Convert 10 hp to kW:**

P(kW) = 0.746 ⋅ 10hp = 7.460 kW

### Metric horsepower to kilowatts

One metric horsepower is equal to 0.73549875 kilowatts:

1 hp(M) = 735.49875 W = 0.73549875 kW

So the power conversion of horsepower to kilowatts is given by:

P(kW) = 0.73549875 ⋅ P(hp)

**Example: Convert 10 hp to kW:**

P(kW) = 0.73549875 ⋅ 10hp = 7.3549875 kW
