Milliwatts to watts Conversion
1 milliwatts (mW) is equal to 0.001 watts (watt).
1 mW = 0.001 watt
or
1 watt = 1000 mW
Formula
To convert a power from milliwatts (mW) to watts (watt), divide the power in milliwatts by 1000
p(watt) = p(mW) / 1000
Examples:
Convert 250 milliwatts to watts:
p(watt) = 250mW / 1000 = 0.25 watt

Frequently asked questions
How do I convert milliwatts to watts?
Divide the value in milliwatts by 1000 to get the result in watts. For example, 5 mW ÷ 1000 = 0.005 watt.
How many watts are in 1 milliwatts?
1 milliwatts (mW) is equal to 0.001 watts (watt).
How do I convert watts back to milliwatts?
Use the inverse operation: multiply the value in watts by 1000 to get the result in milliwatts.
How accurate is the milliwatts to watts conversion?
The converter multiplies by the conversion factor 1000 and rounds the result to 9 decimal places by default. You can increase or reduce the precision with the digits option on this page.
