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. WebAug 31, 2024 · A barometer is a scientific instrument used to measure atmospheric pressure, also called barometric pressure. How do you calculate barometric pressure in mmHg? 1 mmHg = 133.322 pascals (Pa) 1 inHg = 3386.39 pascals (Pa) mmHg value x 133.322 Pa = inHg value x 3386.39 Pa. mmHg value = inHg value x 25.4.
