How to Convert Milliwatts to Kilowatts

To convert a measurement in milliwatts to a measurement in kilowatts, divide the power by the following conversion ratio: 1,000,000 milliwatts/kilowatt.

Since one kilowatt is equal to 1,000,000 milliwatts, you can use this simple formula to convert:

kilowatts = milliwatts ÷ 1,000,000

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

For example, here's how to convert 5,000,000 milliwatts to kilowatts using the formula above.

kilowatts = (5,000,000 mW ÷ 1,000,000) = 5 kW

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

What Is a Milliwatt?

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 thousandths, or 10^-3. Milliwatts can be abbreviated as mW; for example, 1 milliwatt can be written as 1 mW.

What Is a Kilowatt?

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