How is barometric pressure measured

WebAtmospheric pressure is measured in pascals (Pa), or more accurately in hectopascals (hPa), i.e. the equivalent of 100 pascals or 1 millibar, the measurement previously used. It's measured using an instrument called a barometer. The first devices date from 1644 and the experiments of Evangelista Torricelli, who developed the mercury barometer. Web24 nov. 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.
