<< This is the well accepted number that most engineers use when dealing
with gaseous systems. Anyway, whether you use 14.8 or 14.7, the difference
is
less than 1%, and both results give you correct "ballbark" answers. In fact,
maybe
14.8 is truly better. Since 14.7 is based on standard conditions (32deg F
and 1 atm),
after correcting it for a higher temperature, it may be 14.8 PSI.
Well, enough with boring details.

I didn't change the 14.8, which was part of the post to which I was
responding. Besides, my memory for these things is only so good, and
currently I don't use 14.7 psi and scientific STP much. The meteorological
29.92 millibars at 59 degrees F is what we pilots use for performance
calculations, etc.
