## What Is a Microwatt?

A microwatt is a unit used to measure power.

The microwatt is a multiple of the watt, which is the SI derived unit for power. In the metric system, "micro" is the prefix for millionths, or 10-6. Microwatts can be abbreviated as µW; for example, 1 microwatt can be written as 1 µW.

## How Much Is a Microwatt?

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

## How to Convert Microwatts

To convert microwatts to another unit of power, you need to multiply the value by a conversion factor. A conversion factor is a numerical value used to change the units of a measurement without changing the value.[1]

You can find the conversion factors for microwatts in the conversion table below.

Then, multiply the power measurement by the conversion factor to find the equivalent value in the desired unit of measurement.

microwatts × conversion factor = result

You can also use a calculator, such as one of the converters below, for the conversion.
