uV to dBm Calculator

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

arrow dBm to uV

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.
