Voltage from dBm

V=0.00110dBm1050
(dBm)RF power level reference to 1mW
(R) Impedance

The  Voltage from dBm calculator computes the amount of voltage produced based on the dBm power level.

INSTRUCTIONS: Enter the following:

  • (dBm) Power level of the RF signal

Voltage (V): The calculator returns the power level in Watts.  However, this can be automatically converted to compatible units via the pull-down menu.

The Math / Science

The formula for the Voltage from dBm is: 

    V 

where:

  • V = Voltage
  • dBm = power level
