Power Conversion Calculator
Convert between SI, Imperial, electrical, and mechanical power units.
A Power Conversion Calculator is a convenient online tool that helps you convert power values from one unit to another quickly and accurately. Power is a key measurement in electricity, mechanics, physics, and engineering, and it is expressed in different units depending on the application. This calculator removes guesswork and manual calculations, making power conversions simple and reliable.
What Is Power?
Power is the rate at which work is done or energy is transferred over time. It shows how quickly energy is used or produced. In everyday life, power is used to describe electrical devices, engines, machines, and energy systems.
Because different industries and regions use different power units, a power conversion calculator is essential for comparing and understanding power values correctly.

How the Power Conversion Calculator Works
Using a power conversion calculator is simple:
- Enter the power value you want to convert
- Select the original power unit
- Choose the target power unit
- The calculator instantly displays the converted result
Some calculators also allow conversion to multiple units at once for easier comparison.
Power Conversion Formula (Basic Concept)
Power conversion works by converting the input value into a base unit, usually watts, and then converting it into the desired unit.
General formula:
Converted Power = Input Power × Conversion Factor
Examples:
- 1 kilowatt (kW) = 1,000 watts (W)
- 1 horsepower (hp) ≈ 745.7 watts (W)
The calculator applies these conversion factors automatically to ensure accuracy.
