[QUOTE="Mikecr, post: 448089, member: 1521"] I believe ICAO + 78%RH = standard artillery atmosphere (SAA) Pejsa was stuck on this oddity for quite a while, and Gerald may be borrowing from Pejsa's math for his solutions. Personally, I convert all to ICAO. I could post a spreadsheet to do this for you if needed. One thing I notice with this discussion though,, you keep referring to altitude. You already measure & hold station pressure, so there is never any reason to consider altitude. DO NOT ENTER ALTITUDE [/QUOTE]
