and a station elevation 
are given. To calculate altimeter setting, the station pressure must be in units
of millibars 
.
To see how to convert station pressure to millibars see the link below:From the user, a station pressure

To see how to convert station pressure to millibars see the link below:
Also to calculate the altimeter setting, the station elevation must be in units
of 
.
To convert meters to feet, see the equation below:
Then, the altimeter setting can be calculated using the formula below:
Then, the answer can be converted to different pressure units. See the link above to see how to do this.
