Explanation:
Detailed explanation-1: -Meteorologists use a metric unit for pressure called a millibar and the average pressure at sea level is 1013.25 millibars.
Detailed explanation-2: -Since the composition and hence the denity of air varies with the altitude, the pressure exerted by air also varies. The atmosphere pressure decreases with an increase in the altitude. It is due to this reason that the atmospheric pressuer is measured at sea level where it is almost equal square centimeter.
