Atmospheric pressure also called atmospheric pressure after the barometer is the pressure in the Earth's atmosphere. A standard atmosphere is a unit of pressure defined as 101,325 Pa equivalent to 1013.25 millibars, 760 mm Hg, 29.9212 inches Hg, or 14.696 psi.
Atmospheric pressure decreases with altitude. 1 atm is a unit of pressure equal to the pressure exerted by air at a temperature of 15 degrees above sea level, averaged. One atmosphere is also equivalent to 1,013 millibars or 760 millimeters of mercury.
Atmospheric pressure is measured with a barometer using a silicon capacitive pressure sensor with excellent repeatability and long-term stability.
