Volts to dBm Calculator

Use this calculator to convert volts in to dBm.
  • Volt


  • dBm Value

Volts to dBm Calculator is used to convert the RMS voltage value (V) to the power in dBm using the RMS voltage value entered by the user.  The calculator quickly and accurately calculates dBm from RMS voltage (V) for the system having a characteristic impedance of 50 ohms. The calculator uses the following formula: 


Vrms - Represents the root–mean–square value of the electrical signal in Volts.
dBm (decibel-milliwatts) is the decibel unit for measuring power levels with reference to one milliwatt (1 mW). The dBm is a convenient unit; used in radio, audio applications, and other RF applications to measure signal strength.

The Volts to dBm calculator helps to calculate the power in dBm from RMS voltage (V) by entering the RMS voltage value (V). This calculator is a useful tool in wireless and RF applications as well as in EMC measurements, where precise measurement and analysis of signal strength are crucial.
