Enter the rms (root-mean-square) voltage (volts) into the calculator to determine the Peak-To-Peak Voltage. 

Peak-To-Peak Voltage Formula

The following formula is used to calculate the Peak-To-Peak Voltage. 

Vp-p =2.82842712475* Vrms


  • Where Vp-p is the Peak-To-Peak Voltage (volts)
  • Vrms is the rms (root-mean-square) voltage (volts) 

How to Calculate Peak-To-Peak Voltage?

The following two example problems outline the steps and information needed in order to calculate the Peak-To-Peak Voltage.

Example Problem #1:

  1. First, determine the rms (root-mean-square) voltage (volts). In this example, the rms (root-mean-square) voltage (volts) is measured to be 65.
  2. Finally, calculate the Peak-To-Peak Voltage using the formula above: 

Vp-p =2.82842712475* Vrms

Inserting the values from above into the equation yields: 

Vp-p =2.82842712475* 65 = 183.847 (volts)

Example Problem #2: 

Using the same process as the first example, define the variables outlined by the formula. In this case, these values are:

rms (root-mean-square) voltage (volts) = 75

Entering these values into the formula or calculator above gives us:: 

Vp-p =2.82842712475* 75 = 212.132 (volts)
