How to Convert Watt to Microwatt
To convert from Watt (W) to Microwatt (µW), multiply the value by 1,000,000.
Formula: µW = W × 1,000,000
Reverse: W = µW × 0.000001
Step-by-Step Example
- Start with your value in Watt. For example: 5 W
- Multiply by the conversion factor: 5 x 1,000,000
- The result is: 5,000,000 µW
About Watt
The watt (W) is a unit of power. One watt equals 1 watt. UnitConvertLab converts it against every other power unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.
Common uses: power calculations, engineering and science, education.
About Microwatt
The microwatt (µW) is a unit of power. One microwatt equals 1.000000 × 10^-6 watts. UnitConvertLab converts it against every other power unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.
Common uses: power calculations, engineering and science, education.
