Peak to Peak Voltage Calculator
Enter the known values and run the calculation.
Enter the known voltage, choose whether it represents a peak or RMS value, and run the calculation.
The result reports the corresponding peak-to-peak voltage in volts.
Overview
Translate waveform amplitude into peak-to-peak terms for signal integrity and comparison work.
Use this tool to convert a known peak or RMS waveform value into peak-to-peak voltage.
It is useful when a design note, meter reading, and oscilloscope display all describe the same waveform in different ways.
The math and how it's used
The RMS conversion assumes a sinusoidal waveform.
If the waveform is not sinusoidal, use the actual peak relationship instead of the sine-wave RMS factor.
This is a quick waveform-translation tool for moving between the numbers a meter gives you and the amplitude terms a scope or datasheet is using.
The RMS conversion path assumes a sine wave. If the waveform is clipped, pulsed, or intentionally shaped, use the actual measured peaks instead of the sine-wave constant.
What to watch
The RMS conversion path assumes a sine wave. Square, triangle, pulsed, or distorted waveforms do not follow the same constant factor.
If you already know the true positive and negative peaks from a scope trace, use those directly instead of an RMS conversion.
