Web28 dec. 2024 · The torr is an alternative unit used for atmospheric pressures, which is defined as 1/760 of an atmosphere, or 133.3 Pa. In meteorology, millibars are often used, where 1 bar = 100,000 Pa and 1 millibar = 100 Pa. Finally, there are some even more unusual units for pressure, including millimeters of mercury (mmHg), which is defined … Web20 feb. 2024 · This happens because of Pascal’s principle. The total pressure, or absolute pressure, is thus the sum of gauge pressure and atmospheric pressure: (11.6.1) P a b s = P g + P a t m. where P a b s is absolute pressure, P g is gauge pressure, and P a t m is atmospheric pressure. For example, if your tire gauge reads 34 psi (pounds per square …
