## How to Convert Watts to Milliwatts

Convert watts to milliwatts with this simple formula:

Converting a watt power measurement to a milliwatt measurement involves multiplying the power by the conversion ratio to find the result. One watt is equal to 1,000 milliwatts, so to convert simply multiply by 1,000.

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

Watts and milliwatts are both units used to measure power.
