Watts to milliwatts Conversion
1 watts (watt) is equal to 1000 milliwatts (mW).
1 watt = 1000 mW
or
1 mW = 0.001 watt
Formula
To convert a power from watts (watt) to milliwatts (mW), multiply the power in watts by 1000
p(mW) = p(watt) × 1000
Examples:
Convert 300 watts to milliwatts:
p(mW) = 300watt × 1000 = 300000 mW

Frequently asked questions
How do I convert watts to milliwatts?
Multiply the value in watts by 1000 to get the result in milliwatts. For example, 5 watt × 1000 = 5000 mW.
How many milliwatts are in 1 watts?
1 watts (watt) is equal to 1000 milliwatts (mW).
How do I convert milliwatts back to watts?
Use the inverse operation: divide the value in milliwatts by 1000 to get the result in watts.
How accurate is the watts to milliwatts 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.
