## Voltage from DB Formula

The following formula is used to calculate the Voltage from DB.

**V = 10**^{(dBV/20)}

Variables:

- Where V is the Voltage from DB (volts)
- dVB is the total db (decibel volts)

To calculate the voltage from dB, raise 10 to the power of the dBV over 20.

## How to Calculate Voltage from DB?

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

**Example Problem #1:**

- First, determine the total db (decibel volts). In this example, the total db (decibel volts) is measured to be 14.
- Finally, calculate the Voltage from DB using the formula above:

V = 10 ^ (dBV / 20)

Inserting the values from above into the equation yields:

V = 10 ^ (14/ 20) = 5.011 (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 db (decibel volts) = 100

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

V = 10 ^ (100 / 20) = 100,000 (volts)
