Enter the total alternating current voltage (volts) into the calculator to determine the DC Voltage from AC Voltage.

## DC Voltage from AC Voltage Formula

The following formula is used to calculate the DC Voltage from AC Voltage.

Vdc = Vac * .636

Variables:

• Where Vdc is the DC Voltage from AC Voltage (volts)
• Vac is the total alternating current voltage (volts)

To calculate DC voltage from AC voltage, multiply the AC voltage by .636.

## How to Calculate DC Voltage from AC Voltage?

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

Example Problem #1:

1. First, determine the total alternating current voltage (volts). In this example, the total alternating current voltage (volts) is measured to be 60.
2. Finally, calculate the DC Voltage from AC Voltage using the formula above:

Vdc = Vac * .636

Inserting the values from above into the equation yields:

Vdc = 60 * .636 = 38.16 (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:

total alternating current voltage (volts) = 11

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

Vdc = 11 * .636 = 6.996 (volts)
