WebDec 28, 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 … WebIn imperial units the Standard Atmospheric Pressure is 14.696 psi. 1 atm = 1.01325 bar = 101.3 kPa = 1.013 105 Pa = 14.696 psi (lbf/in2)= 760 mmHg =10.33 mH2O = 760 torr = 29.92 inHg = 1013 mbar = 1.0332 kgf/cm2 = …

The bar is a metric unit of pressure, but not part of the International System of Units (SI). It is defined as exactly equal to 100,000 Pa (100 kPa), or slightly less than the current average atmospheric pressure on Earth at sea level (approximately 1.013 bar). By the barometric formula, 1 bar is roughly the atmospheric … See more The bar is defined using the SI derived unit, pascal: 1 bar ≡ 100,000 Pa ≡ 100,000 N/m . Thus, 1 bar is equal to: • 1,000,000 Ba (barye) (in cgs units); and 1 bar is … See more Atmospheric air pressure where standard atmospheric pressure is defined as 1013.25 mbar, 101.325 kPa, 1.01325 bar, which is about 14.7 pounds per square inch. Despite the millibar not being an SI unit, meteorologists and weather reporters worldwide have … See more The word bar has its origin in the Ancient Greek word βάρος (baros), meaning weight.
