How to Convert Milliwatt to Microwatt
To convert from Milliwatt (mW) to Microwatt (µW), multiply the value by 1,000.
Formula: µW = mW × 1,000
Reverse: mW = µW × 0.001
Step-by-Step Example
- Start with your value in Milliwatt. For example: 5 mW
- Multiply by the conversion factor: 5 x 1,000
- The result is: 5,000 µW
About Milliwatt
