https://en.wikipedia.org/wiki/Atmospheric_pressure

WebAtmospheric pressure, also known as air pressure or barometric pressure (after the barometer), is the pressure within the atmosphere of Earth. The standard atmosphere (symbol: atm) is a unit of pressure defined as 101,325 Pa (1,013.25 hPa), which is equivalent to 1,013.25 millibars, 760 mm Hg, 29.9212 inches Hg, or 14.696 psi.

WebThe weight of air above a given area on Earth’s surface is called atmospheric pressure. It is an important factor influencing Earth’s weather and climate. Atmospheric pressure can be measured with an instrument called a barometer and thus is also known as barometric pressure. It is usually measured in millibars (mb) or kilopascals (kPa).
