==How to convert watts to dBm==
The power P(dBm) in dBm is equal to 10 times the base 10 logarithm of 1000 times the power P(W) in watts (W) divided by 1 watt (W):<br />
P(dBm) = 10 · log10( 1000 · P(W) / 1W) = 10 · log10( P(W) / 1W) + 30<br />
so<br />
 1W = 30dBm
Example<br />
Convert 20 watts to dBm:<br />
 P(dBm) = 10 · log10(1000·20W) = 43.0103dBm
