## Station Pressure Formula

The following formula is used to calculate the Station Pressure.

Pstn = Pa * ( ( 288-.0065*h)/288)^5.2561

- Where Pstn is the Station Pressure (inHg)
- Pa is the altimeter pressure (inHg)
- h is the station height (m)

## How to Calculate Station Pressure?

The following two example problems outline how to calculate the Station Pressure.

**Example Problem #1:**

- First, determine the altimeter pressure (inHg). In this example, the altimeter pressure (inHg) is given as 1.25.
- Next, determine the station height (m). For this problem, the station height (m) is given as 1000.
- Finally, calculate the Station Pressure using the equation above:

Pstn = Pa * ( ( 288-.0065*h)/288)^5.2561

Inserting the values from above and solving the equation:

Pstn = 1.25 * ( ( 288-.0065*1000)/288)^5.2561 = 1.108 (inHG)

**Example Problem #2: **

Using the same process as above, first define the variables required by the formula. In this case, these values are:

altimeter pressure (inHg) = .65

station height (m) = 4000

Entering these values yields:

Pstn = .65 * ( ( 288-.0065*4000)/288)^5.2561 = .395 (inHg)
