How to use it

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.

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 Formula used Vpp = 2 \times Vp Vpp = 2 \times \sqrt(2) \times Vrms 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.

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.
