Results in Milliwatts:

1 kW = 1,000,000 mW

How to Convert Kilowatts to Milliwatts

To convert a measurement in kilowatts to a measurement in milliwatts, multiply 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:

milliwatts = kilowatts × 1,000,000

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

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

milliwatts = (5 kW × 1,000,000) = 5,000,000 mW

How Many Milliwatts Are in a Kilowatt?

There are 1,000,000 milliwatts in a kilowatt, which is why we use this value in the formula above.

1 kW = 1,000,000 mW

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

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.

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.
