Convert Watts to Milliwatts

Watts → Milliwatts
W × 1000 = mW mW × 0.001 = W

To convert watts (W) to milliwatts (mW), multiply the watts value by 1000. One watts equals 1000 milliwatts; one milliwatts equals 0.001 watts. The conversion is a linear scaling with no offset, so the same factor applies to any value.
