Peak to Peak Voltage Calculator

This calculator shows the peak-to-peak voltage (VP-P) value from the peak voltage, RMS voltage, or average voltage.

Inputs

Volts (V)

Output

Voltage Peak-to-Peak (VP-P)

Volts (V)

Overview

The peak-to-peak voltage calculator finds the peak-to-peak voltage, 

VP−P$$V_{P-P}$$

, from the peak voltage, 

VP$$V_P$$

, rms voltage, 

Vrms$$V_{rms}$$

 or average voltage, 

Vavg$$V_{avg}$$

. 

Equations

VP−P=2∗VP$$V_{P-P}=2\ast V_P$$

VP−P=22–√∗Vrms=2.828∗Vrms$$V_{P-P}=2\sqrt{2}\ast V_{rms}=2.828\ast V_{rms}$$

VP−P=π∗Vavg=3.414∗Vavg$$V_{P-P}=\pi \ast V_{avg}=3.414\ast V_{avg}$$

VP$$V_P$$

: The maximum instantaneous value of a function as measured from the zero-volt level. For the waveform shown above, the peak amplitude and peak value are the same, since the average value of the function is zero volts.

VP−P$$V_{P-P}$$

: The full voltage between positive and negative peaks of the waveform; that is, the sum of the magnitude of the positive and negative peaks.

Vrms$$V_{rms}$$

: The root-mean-square or effective value of a waveform.

Vavg$$V_{avg}$$

: The level of a waveform defined by the condition that the area enclosed by the curve above this level is exactly equal to the area enclosed by the curve below this level.
