Enter the gauge pressure (psi) and the base pressure (psi) into the Calculator. The calculator will evaluate the Pressure Factor.

## Pressure Factor Formula

PF = (GP + ATM) / BP

Variables:

- PF is the Pressure Factor ()
- GP is the gauge pressure (psi)
- BP is the base pressure (psi)

To calculate the Pressure Factor, sum the gauge and atmospheric pressure, then divide by the base pressure.

## How to Calculate Pressure Factor?

The following steps outline how to calculate the Pressure Factor.

- First, determine the gauge pressure (psi).
- Next, determine the base pressure (psi).
- Next, gather the formula from above = PF = (GP + ATM) / BP.
- Finally, calculate the Pressure Factor.
- 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.

gauge pressure (psi) = 4.5

base pressure (psi) = 14
