Convert Milliwatts to Watts

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

To convert milliwatts (mW) to watts (W), multiply the milliwatts value by 0.001. 1 mW = 0.001 W, and 1 W = 1000 mW. The conversion is a linear scaling with no offset, so the same factor applies to any value.

Going the other way? Convert W to mW.
