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
The use of millibars is slowly giving way to the equivalent. SI unit of hectoPascals (hPa). The mean atmospheric pressure at. sea level is given equivalently as P = 1.013x105 Pa = 1013 hPa =. 1013 mb = 1 atm = 760 torr.
