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!
