As an example, consider a unit area of 1 square inch. At sea level, the weight of the air above this unit area would (on average) weigh 14.7 pounds! That means pressure applied by this air on the unit area would be 14.7 pounds per square inch.Meteorologists use a metric unit for pressure called a millibar and the average pressure at sea level is 1013.25 millibars.t sea level, the weight of the air above this unit area would (on average) weigh 14.7 pounds!
