Vpp to Vp Calculator

This tool converts a peak-to-peak voltage to peak voltage.

Sine voltage

Referring to the picture of a sine wave above, there are three different voltage levels:

  1. Peak Voltage (Vp)
  2. Peak-to-peak Voltage (Vpp)
  3. RMS Voltage (VRMS)


Vp = Vpp/2

Vp = √2 * VRMS


Peak voltage Vp is always half the value of the peak-to-peak voltage Vpp. It doesn’t matter if it’s a sine, triangle or square wave.
