How to Convert Milliwatts to Megawatts

To convert a milliwatt measurement to a megawatt measurement, multiply the power by the conversion ratio. One milliwatt is equal to 1.0E-9 megawatts, so use this simple formula to convert:

megawatts = milliwatts × 1.0E-9

The power in megawatts is equal to the milliwatts multiplied by 1.0E-9.

For example, here's how to convert 5 milliwatts to megawatts using the formula above.
5 mW = (5 × 1.0E-9) = 5.0E-9 MW

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

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.

Megawatts

One megawatt is the power equal to 1,000,000 watts, or the energy consumption at a rate of 1,000,000 joules per second.

The megawatt is a multiple of the watt, which is the SI derived unit for power. In the metric system, "mega" is the prefix for 109. Megawatts can be abbreviated as MW, for example 1 megawatt can be written as 1 MW.
