dBm/Hz to nV/sqrt Hz Calculator

This tool converts dBm per Hz to nV per root(Hz)

Example Use

A spectrum analyzer provides amplitude measurement in terms of dBm with an associated resolution bandwidth. Use this calculator to find the dBm value in a 1 Hz RBW or dBm/Hz.

dBm/Hz can be converted to nV/√Hz using the calculator. As an example, -150 dBm/Hz converts to 7.07 nV/√Hz.

In this calculation the default impedance value of 50 ohm is used. You can also change the value of the impedance.

As well the units can be changed to any of the following:

  • nV/√Hz
  • uV/√Hz
  • mV/√Hz
  • V/√Hz
