Enter the altimeter pressure (inHg) and the station height (m) into the calculator to determine the Station Pressure. 

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:

  1. First, determine the altimeter pressure (inHg). In this example, the altimeter pressure (inHg) is given as 1.25.
  2. Next, determine the station height (m). For this problem, the station height (m) is given as 1000.
  3. 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)
