Web8 feb. 2024 · Such a device is known as a barometer. Normal atmospheric pressure is in the range of 1 atm = 101.325 kilopascal (kPa) = 760 millimeters of mercury (mm Hg or torr) = 14.7 pounds per square inch (psi). See the Resources for a conversion tool to work between these and other units of pressure. WebhPa – Hectopascal Pressure Unit. Hectopascal is a 100x multiple of the pascal, which is the SI unit for pressure. The hectopascal is the international unit for measuring atmospheric or barometric pressure. 1 hectopascal equals 100 pascals. Due to its low value the hectopascal is ideal for use as a measure of atmospheric pressure and other …
