Watt to Milliwatt
1 W = 1,000 mW
One watt equals 1,000 milliwatts, and one milliwatt equals 0.001 watts.
Watt to Milliwatt formula
mW = W × 1000
To convert watts to milliwatts, multiply the value by 1000. One watt equals 1,000 milliwatts.
Step-by-step examples
Convert 1 watts to milliwatts
- 1Start with the value in watts: 1 W.
- 2Multiply by the conversion factor 1000.
- 31 × 1000 = 1,000 mW.
Result: 1 W = 1,000 mW
Convert 10 watts to milliwatts
- 1Start with the value in watts: 10 W.
- 2Multiply by the conversion factor 1000.
- 310 × 1000 = 10,000 mW.
Result: 10 W = 10,000 mW
Convert 100 watts to milliwatts
- 1Start with the value in watts: 100 W.
- 2Multiply by the conversion factor 1000.
- 3100 × 1000 = 100,000 mW.
Result: 100 W = 100,000 mW
