How to Convert Milliwatts to Watts
The milliwatt and watt are both units of power. By definition, 1 milliwatt equals exactly 1000000 watts. This means to convert milliwatts to watts, you multiply by 1000000.
Formula
Step-by-Step Example
Convert 5 mW to watts:
We need to convert milliwatts to watts
Since 1 mW = 1000000 W, multiply by 1000000
5 × 1000000 = 5000000
5 mW = 5000000 W

About These Units
Milliwatt (mW)
A milliwatt (mW) equals 0.001 watts or one-thousandth of a watt. Milliwatts measure laser pointer power (1-5 mW), wireless signal strength (WiFi: 30-100 mW), LED indicator lights, and low-power electronics. Bluetooth devices typically transmit at 1-100 mW.
Watt (W)
The watt (W) is the SI unit of power equal to one joule per second. Watts measure electrical power consumption (LED bulb: 10W, microwave: 1000W), light bulb brightness, and device power ratings. One kilowatt equals 1,000 watts. Named after inventor James Watt.
