Milliwatt to Watt
1 mW = 0.001 W
One milliwatt equals 0.001 watts, and one watt equals 1,000 milliwatts.
Milliwatt to Watt formula
W = mW × 0.001
To convert milliwatts to watts, multiply the value by 0.001. One milliwatt equals 0.001 watts.
Step-by-step examples
Convert 1 milliwatts to watts
- 1Start with the value in milliwatts: 1 mW.
- 2Multiply by the conversion factor 0.001.
- 31 × 0.001 = 0.001 W.
Result: 1 mW = 0.001 W
Convert 10 milliwatts to watts
- 1Start with the value in milliwatts: 10 mW.
- 2Multiply by the conversion factor 0.001.
- 310 × 0.001 = 0.01 W.
Result: 10 mW = 0.01 W
Convert 100 milliwatts to watts
- 1Start with the value in milliwatts: 100 mW.
- 2Multiply by the conversion factor 0.001.
- 3100 × 0.001 = 0.1 W.
Result: 100 mW = 0.1 W
