decibel watt (dBW)

Decibel Watt (dBW) is the specification of a power level in decibels (dB), related to 1 W.

Decibel Watt is calculated from the tenfold logarithm of the power in Watt (W): dBW = 10logW. Accordingly, 1 W corresponds to 0 dBW. 2 W corresponds to 3.0102 dBW, 10 W to 10 dBW, 100 W to 20 dBW and 1,000 W to 30 dBW.

The unit decibel watt (dBW) is used, among other things, in broadcasting technology and for the transmission power of transponders in satellite systems.
