dBm is defined as power ratio in decibel (dB) referenced to one milliwatt (mW). It is an

abbreviation for dB with respect to 1 mW and the "m" in dBm stands for milliwatt.

dBm is different from dB. dBm represents absolute power, whereas in audio engineering the

decibel is usually a voltage ratio of two values and is used then to represent gain or attenuation

of an audio amplifier, or an audio damping pad.

What is the difference between DB and DBMS?

dBm us almost exactly the same as dB. The only difference is that there is a reference of 1 Watt = 0 dB, and 1 mW = 0 dBm. Sorry but that is incorrect. db is a ratio and not an absolute value, by it self it means nothing. you got the dbm part right, 1 mW = 0 dbm and it is an absolute value.


How do you convert 10W to dBm?

PdBm = 10*log10(1000*10W) = 40dBm
