Atmospheric pressure at sea level averages about 14.5 psi, which is about
one ton per square foot. At an elevation of 1122 feet above sea level,
it averages about 0.6 psi less than that. But the pressure at any level
in the building should be just about the same as the pressure outside the
building at that level, unless the pressure in the building is
intentionally altered.
