WebJul 7, 2015 · Atmospheric pressure — or barometric pressure — is simply the weight of the air at ground level. It’s a little easier to understand when you think about the concept of water pressure first. As you get deeper in water, the pressure increases. This is because as you descend, the built up weight of the water on top of you increases. 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.
