feet (304.8 m) increase in elevation.

At (5500' elevation), "standard" air pressure
is about 12 psi (24.42 in. Hg), not the 14.7 psi
(29.92 in. Hg) found at sea level.

"From sea-level to about 3,000 feet / 914
meters elevation, atmospheric pressure
feet / 0.1 bars per 1000 meters of altitude,

therefore our 29.92 inches of Mercury /
1.013 bars barometer reading at sea-level
now becomes about 27 inches of
Mercury / 0.914 bars.

At 5,000 feet / 1500 meters, about 25
inches of Mercury / 0.84 bars , and 20.6
inches of Mercury / 0.69 bars at 10,000
feet / 3000 meters.
