How barometric pressure is measured

Web24 de nov. de 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.
