How to Convert Kilowatts to Horsepower
To convert kilowatts to horsepower, multiply the power by the following conversion ratio: 1.3410221 horsepower/kilowatt.
Since one kilowatt is equal to 1.3410221 horsepower, you can use this simple formula to convert:
The power in horsepower is equal to the power in kilowatts multiplied by 1.3410221.
For example, here's how to convert 150 kilowatts to horsepower using the formula above.
How Many Horsepower Are in a Kilowatt?
There are 1.3410221 horsepower in a kilowatt, which is why we use this value in the formula above.
Our kilowatt to horsepower calculator automatically converts your power measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Kilowatts and horsepower are both units used to measure power. Keep reading to learn more about each unit.
What Is a Kilowatt?
A kilowatt is a unit of power equal to 1,000 watts (W), the base unit for power. Equal to 1,000 Watts (1 kJ/s). [1]
The kilowatt is classified as a metric and SI-compatible unit of power. Kilowatts can be abbreviated as kW; for example, 1 kilowatt can be written as 1 kW.
In the metric system, "kilo" is the standard SI prefix for thousands, or 10³. This makes the kilowatt (kW) a convenient decimal multiple of the watt (W).
In practice, kilowatts (kW) are widely used across large-scale industrial, bulk, and macro-level power specifications within SI metric workflows, engineering documentation, and technical data sheets.
What Is a Horsepower?
A horsepower is a unit of power equal to 745.6998716 watts (W), the base unit for power. Imperial mechanical horsepower (550 ft·lbf/s ≈ 745.7 W). [2]
The horsepower is classified as a US customary and imperial unit of power. Horsepower can be abbreviated as hp; for example, 1 horsepower can be written as 1 hp.
When working with horsepower (hp) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, horsepower (hp) are widely used across standard power applications within US customary and imperial workflows, engineering documentation, and technical data sheets.
When converting power between kilowatts (kW) and horsepower (hp), keep full floating-point precision (1 kW = 1.3410221 hp; 1 hp = 0.7456999 kW) during intermediate calculations and round only the final horsepower figure to match your instrument tolerance.
