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. 1 W = 1000 mW, and 1 mW = 0.001 W. The conversion is a linear scaling with no offset, so the same factor applies to any value.

Going the other way? Convert mW to W.
