## How to Convert Kilowatts to Horsepower

To convert a kilowatt measurement to horsepower, use one of the formulas below.

### Kilowatts to Mechanical Horsepower

Formula to convert kilowatts to mechanical horsepower:

hp(I) = kilowatts ÷ 0.7457

Since mechanical horsepower is equal to 0.7457 kilowatts, the formula to find mechanical horsepower is the power in kilowatts divided by 0.7457.

**For example,**here's how to convert 5 kilowatts to mechanical horsepower.

### Kilowatts to Electric Horsepower

Formula to convert kilowatts to electric horsepower:

hp(E) = kilowatts ÷ 0.746

Since electric horsepower is equal to 0.746 kilowatts, the formula to find electric horsepower is the power in kilowatts divided by 0.746.

**For example,**here's how to convert 5 kilowatts to electric horsepower.

### Kilowatts to Metric Horsepower

Formula to convert kilowatts to metric horsepower:

hp(M) = kilowatts ÷ 0.735499

Since metric horsepower is equal to 0.735499 kilowatts, the formula to find metric horsepower is the power in kilowatts divided by 0.735499.

**For example,**here's how to convert 5 kilowatts to metric horsepower.

### Kilowatts to Boiler Horsepower

Formula to convert kilowatts to boiler horsepower:

hp(S) = kilowatts ÷ 9.8095

Since boiler horsepower is equal to 9.8095 kilowatts, the formula to find boiler horsepower is the power in kilowatts divided by 9.8095.

**For example,**here's how to convert 5 kilowatts to boiler horsepower.

### How Many Horsepower Are in a Kilowatt?

There are **1.341022** horsepower in a kilowatt, which is why we use this value in the formula above.

1 kW = 1.341022 hp

Kilowatts and horsepower are both units used to measure power. Keep reading to learn more about each unit of measure.

## Kilowatts

One kilowatt is the power equal to 1,000 watts, or the energy consumption at a rate of 1,000 joules per second.

The kilowatt is a multiple of the watt, which is the SI derived unit for power. In the metric system, "kilo" is the prefix for thousands, or 10^{3}. Kilowatts can be abbreviated as *kW*; for example, 1 kilowatt can be written as 1 kW.

## Horsepower

Electric and mechanical are the most commonly used types. One electric horsepower is equivalent to 746 watts and one mechanical horsepower is equivalent to 745.699872 watts.

### Mechanical Horsepower

Mechanical horsepower is often used to measure the output of engines and motors in North America. One mechanical horsepower is equal to 745.69987158227022 watts.

The mechanical horsepower is a US customary and imperial unit of power. Mechanical horsepower can be abbreviated as *hp(I)*; for example, 1 mechanical horsepower can be written as 1 hp(I).

### Electric Horsepower

Electric horsepower is used to measure the output of electric motors and other electrical machines in the US. One electric horsepower is equal to exactly 746 watts.

The electric horsepower is a US customary and imperial unit of power. Electric horsepower can be abbreviated as *hp(E)*; for example, 1 electric horsepower can be written as 1 hp(E).

### Metric Horsepower

One metric horsepower is the power needed to one metric horsepower as the lift a 75 kilogram mass at at one meter per second.^{[1]} One metric horsepower is equal to 735.49875 watts.

The metric horsepower is a non-SI metric unit for power. Metric horsepower can be abbreviated as *hp(M)*, and are also sometimes abbreviated as *PS*, *cv*, *hk*, *pk*, *ks*, or *ch*. For example, 1 metric horsepower can be written as 1 hp(M), 1 PS, 1 cv, 1 hk, 1 pk, 1 ks, or 1 ch.

### Boiler Horsepower

Boiler horsepower is used to measure the power of a boiler to generate steam.
One boiler horsepower is equal to the power needed to evaporate 34.5 pounds in one hour.^{[2]}

Boiler horsepower can be abbreviated as *hp(S)*; for example, 1 boiler horsepower can be written as 1 hp(S).

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 horses.^{[3]} Horsepower were later used to measure the power output of piston and turbine engines and electrical motors.
