Introduction dBm dBW

0 dBm = 1 mW

x dBm = 10 log (P / 1 mW)
P mW = 10^(x/10)


P (mw)        x dBm
--------------------
1              0
10            10
100           20
1000          30

P (mw)        x dBm
--------------------
1              0
0.1          -10
0.01         -20
0.001        -30
