Enter the total dB and the total length (in) into the Calculator. The calculator will evaluate the Db Per Inch.

## Db Per Inch Formula

dBi = dB/L

Variables:

- dBi is the Db Per Inch (dB/in)
- dB is the total dB
- L is the total length (in)

To calculate Db Per Inch, divide the total decibels by the total length.

## How to Calculate Db Per Inch?

The following steps outline how to calculate the Db Per Inch.

- First, determine the total dB.
- Next, determine the total length (in).
- Next, gather the formula from above = dBi = dB/L.
- Finally, calculate the Db Per Inch.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

total dB = 120

total length (in) = 100
