Enter the peak voltage (volts) and into the calculator to determine the Average Voltage. 

Average Voltage Formula

The following formula is used to calculate the Average Voltage. 

Vave = Vp * .637

Variables:

  • Where Vave is the Average Voltage (volts)
  • Vp is the peak voltage (volts) 

To calculate the average voltage, multiply the peak voltage by .637.

This formula calculates the average voltage of a sinusoidal voltage wave.

How to Calculate Average Voltage?

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

Example Problem #1:

  1. First, determine the peak voltage (volts). In this example, the peak voltage (volts) is measured to be 50.
  2. Finally, calculate the Average Voltage using the formula above: 

Vave = Vp * .637

Inserting the values from above into the equation yields: 

Vave = 50 * .637 = 31.85 (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:

peak voltage (volts) = 100

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

Vave = Vp * .637 = 63.7 (volts)
