How to convert power in milliwatts (mW) to watts (W).

One watt is equal to 1000 milliwatts:

1W = 1000mW

milliwatts to watts conversion formula

The power in watts P(W) is equal to the power in milliwatts P(mW), divided by 1000:

P(W) = P(mW) / 1000

Convert 5mW to watts:

P(W) = 5mW / 1000 = 0.005W
