Use this calculator to convert from Microvolt (uV) to dBm.
Note: the impedance will have to be specified and the default value is 50 ohm
Sometimes a radio manufacturer will specify receiver sensitivity in uV and it’s useful to convert to dBm. It can then be used in a receiver chain sensitivity analysis.
For example, the sensitivity of the UV-5R is 0.2 uV. This is equivalent to -121 dBm.
