WebNov 24, 2024 · Atmospheric pressure (P atm) is the weight of the air as the Earth’s gravity pulls it toward its center. It is heaviest at sea level (more atmosphere above it), which is measured at 14.7psi (1.01325 bar). At higher altitudes, atmospheric pressure is different, so it’s important to know the pressure at your altitude. WebBarometric pressure sensors instead measure absolute air pressure. This is the air’s pressure in relation to a perfect vacuum. A classic aneroid barometer Technology For much of our history, barometers depended on the behaviour of mercury or some other liquid in response to changing air pressure.
