How to Convert Kilowatts to Milliwatts

To convert a kilowatt measurement to a milliwatt measurement, multiply the power by the conversion ratio. One kilowatt is equal to 1,000,000 milliwatts, so use this simple formula to convert:

milliwatts = kilowatts × 1,000,000

The power in milliwatts is equal to the kilowatts multiplied by 1,000,000.

For example, here's how to convert 5 kilowatts to milliwatts using the formula above.
5 kW = (5 × 1,000,000) = 5,000,000 mW

Kilowatts and milliwatts 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 103. Kilowatts can be abbreviated as kW, for example 1 kilowatt can be written as 1 kW.

Milliwatts

One milliwatt is the power equal to 1/1,000 of a watt, or the energy consumption at a rate of 1/1,000 of a joule per second.

The milliwatt is a multiple of the watt, which is the SI derived unit for power. In the metric system, "milli" is the prefix for 10-3. Milliwatts can be abbreviated as mW, for example 1 milliwatt can be written as 1 mW.
