A: The normal air pressure at sea level is 14.7 pounds per square inch. Standard atmospheric pressure can also be expressed using different units, including 1013.25 millibars, 1013.25 hectoPascals, 760 millimeters of mercury and 29.92 inches of mercury. Continue Reading
Matthew Bennett, BSc in Physics from UC in Christchurch, New Zealand. Views. Atmospheric pressure at sea level is approximately 100,000 pascals (101,325 Pa by definition.) Air pressure is usually measured in hectopascals (hPa), the hecto prefix corrsponding to 100 (a hecatre is a square with 100m sides), so 1 atmosphere is approximately 1000 hPa. A pascal is the SI unit for pressure, defined as 1 newton per square metre.
