Power Converter
Convert between watts, kilowatts, megawatts, and horsepower with precision. Free online power converter tool.
This free tool allows you to convert between different units of power including watts (W), kilowatts (kW), megawatts (MW), and horsepower (hp). Simply enter your value and select the units to convert from and to.
How This Tool Works
Our power converter uses precise conversion factors to convert between different units of power:
- 1 Kilowatt (kW) = 1,000 Watts (W)
- 1 Megawatt (MW) = 1,000,000 Watts (W)
- 1 Horsepower (hp) = 745.7 Watts (W)
The calculator ensures accuracy by first converting the input value to watts (the base unit), then converting to the desired output unit.
