Web8 feb. 2024 · Such a device is known as a barometer. Normal atmospheric pressure is in the range of 1 atm = 101.325 kilopascal (kPa) = 760 millimeters of mercury (mm Hg or torr) = 14.7 pounds per square inch (psi). See the Resources for a conversion tool to work between these and other units of pressure. Web7 apr. 2024 · Barometric pressure is the weight of the atmosphere pressing down on the Earth. Since the pressure depends upon the depth of the atmosphere above the point where you're measuring the pressure, the pressure decreases as you go higher. Air pressure is affected by atmospheric density, which is related to the air's temperature, …
