W, dBW and dBm conversion online calculator

dBw is the same as dBm, dBw is a unit that represents the absolute value of power (based on 1W power, dBm is based on 1mW)

The formula for calculating dBw is:

Conversion of dBw and dBm: 0 dBw = 10log1 W = 10log1000 mw = 30 dBm

dbm as a function of mw

P = 10 log_10 (p/p_0)                 p_0, dBW = 1 W ; p_0, dBm = 1 mW
P =  dBW
Power :   P =  dBm
p =  W
