dBm means "decibels relative to 1 mW". B is the symbol for the unit bel, and decibel is 1/10th of a bel. Bels are used to measure ratios between two measurements, not an absolute measurement by themselves. In this case you're measuring relative to 1 mW.
So, for instance, if a device is producing 100 mW, this will be 100 times your reference of 1 mW. "100 times" the power is equal to 20 decibels, so this would be 20 dBm.

What is the difference between Dbi and Dbm?
There are a few terms that need to be understood. [dBm,dBd,dBi and dB] For antennas, a common reference unit is the dBi, which states the gain of an antenna as referenced to an ISOTROPIC source. An Isotropic source is the perfect omnidirectional radiator, a true "Point Source", and does not exist in nature. Consider it a source which is the center of the sphere and the energy is coming equally out of it as a sphere. Now in reality nothing like that exists. It's also 2.41 dB BIGGER than the next common unit of antenna gain, the dBd, When you convert that to a real antenna. So a simple dipole antenna has a gain of 2.41dBi, and a gain of 0dBd, since we're comparing it to itself. Now lets talk about dBm, dBm is not is reference to anything else but the used as an actual gain ( say amplifiers ) , P(dBm)=10*LOG(1000*Power in milliwatts,10), an amp with an output of 30dBm puts out 1 Watt. It is not in refernce to two power level but directly correlating the gain of a device. Now when you talk about a dB it is a relative measure of two different power levels. 10log (p1/p2, 10).

How do you convert dBm to dB?
the first convert the power in dBm to MW, the define of dBm=10 log (P MW) -10 log ( 1mw). example: let P=-2 dBm convert this to dB? answer: Pmw= inv log(-2/10)=0.630mw*1000 micw/mw=630 microw 10log(630)=28dB

How 1mWatt equals 0dBm?
The decibel-milliwatt (dBm) scale is a logarithmic unit used to express power levels relative to 1 milliwatt (mW). Specifically, 0 dBm is defined as the power level equal to 1 mW. Therefore, when the power is exactly 1 mW, it translates to 0 dBm, as dBm is calculated using the formula ( \text{dBm} = 10 \times \log_{10}(\text{Power in mW}) ); thus, ( \log_{10}(1) = 0 ), resulting in 0 dBm.
