How to Convert Milliwatts to Watts Using an Easy Conversion Formula

Convert milliwatts to watts with this simple formula:

watts = milliwatts × 0.001

Converting a milliwatt power measurement to a watt measurement involves multiplying your power by the conversion ratio to find the result. A milliwatt is equal to 0.001 watts, so to convert simply multiply by 0.001.

For example:
5 mW = (5 × 0.001) = 0.005 W

Milliwatts and watts are both units used to measure power. Learn more about power and find more power measurement conversion calculators. A milliwatt is a power measurement and can be abbreviated as mW, for example 1 mW. A watt is a power measurement and can be abbreviated as W, for example 1 W.

A watt is equal to the rate of energy of one joule per second and is a standard unit of power measurement under the International System of Units (SI). You might also find our watts to amps calculator or our watts to kilowatt-hours calculator useful.
