dBµV (decibel-microvolts) is a unit of power in decibels when referenced to 1 microvolt per meter. It is generally used for electric field intensity measurement.

dBm (decibel-milliwatts) is a unit used to indicate that a power level is expressed in decibels (dB) with reference to one milliwatt (mW).

dBm is expressed as: 

       dBm = dBµV – 10log10 (Z) + 90


Z is the system impedance
