Enter the Average Voltage (volts) into the calculator to determine the Maximum Voltage. 

Maximum Voltage Formula

The following formula is used to calculate the Maximum Voltage. 

Vmax = Vave /.637


  • Where Vmax is the Maximum Voltage (volts)
  • Vave is the Average Voltage (volts) 

To calculate a max voltage, divide the average voltage by .637.

How to Calculate Maximum Voltage?

The following two example problems outline how to calculate the Maximum Voltage.

Example Problem #1:

  1. First, determine the Average Voltage (volts). In this example, the Average Voltage (volts) is measured to be 45.
  2. Finally, calculate the Maximum Voltage using the formula above: 

Vmax = Vave /.637

Inserting the values from above and solving the equation with the imputed values gives: 

Vmax =45/.637 = 70.64(volts)

Example Problem #2: 

Using the same process as example problem 1, we first define the variables outlined by the formula. In this case, the values are:

Average Voltage (volts) = 100

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

Vmax = 100 /.637 = 156.98 (volts)
