One Atmospheric Pressure
qThe average air
pressure at sea level is equivalent to the pressure produced
by a column of water about 10 meters (or about 76 cm of
mercury column).
qThis standard
atmosphere pressure is often expressed as 1013 mb
(millibars), which means a pressure of about 1 kilogram per
square centimeter.
