dBm to Amplitude Calculator

In this article we show how to convert from Power in dBm to Amplitude in Volt

Sine voltage

Referring to the picture of a sine wave above, there are three different Amplitudes shown

  1. Peak amplitude (Vpeak)
  2. Peak-to-peak amplitude (Vpeak-to-peak)
  3. RMS amplitude (VRMS)

Use the calculator below to calculate each of these from the dBm value.
