This tool converts a peak-to-peak voltage to peak voltage for an AC waveform.

Referring to the picture of a sine wave above, there are three different voltage levels:
- Peak Voltage (Vp)
- Peak-to-peak Voltage (Vpp)
- RMS Voltage (VRMS)
Formula
Vp = Vpp/2
Vp = √2 * VRMS
Background
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.
For an AC waveform the peak voltage represents the maximum and minimum excursions of the waveform. If it’s symmetric about zero or DC, then Vp = -Vp. However if there’s a DC component to the signal, then this equation does not apply.
