^ a b c This is the customarily accepted value for cmвЂ“H 2O, 4В вЊ.For example, underwater pressure of 3 ata would mean that this pressure includes 1 atm of air pressure and thus 2 atm due to the water. The ata unit is used in place of atm to indicate the total pressure of the system, compared to a vacuum. в‰Ў 101 325 pascals (Pa) в‰Ў 1.013 25 bar в‰€ 1.033 kgf/cm 2 в‰€ 1.033 technical atmosphere в‰€ 10.33 m H 2O, 4В вЊ в‰€ 760 mmHg, 0В вЊ, subject to revision as more precise measurements of mercury's density become available в‰Ў 760 torr (Torr) в‰€ 29.92 inHg, 0В вЊ, subject to revision as more precise measurements of mercury's density become available в‰€ 406.782 in H 2O, 4 вЊ в‰€ 14.6959 pounds-force per square inch (lbf/in 2) в‰€ 2 116.22 pounds-force per square foot (lbf/ft 2) = 1 ata (atmosphere absolute). Pressure units and equivalencies Pressure unitsДЄ pressure of 1В atm can also be stated as: In chemistry and in various industries, the reference pressure referred to in standard temperature and pressure (STP) was commonly 1В atm (101.325В kPa) but standards have since diverged in 1982, the International Union of Pure and Applied Chemistry (IUPAC) recommended that for the purposes of specifying the physical properties of substances, standard pressure should be precisely 100 kPa (1 bar). In addition, the CGPM noted that there had been some misapprehension that it 'led some physicists to believe that this definition of the standard atmosphere was valid only for accurate work in thermometry.' This defined both temperature and pressure independent of the properties of particular substance.

In 1954, the 10th General Conference on Weights and Measures (CGPM) adopted standard atmosphere for general use and affirmed its definition of being precisely equal to 1 013 250 dynes per square centimetre ( 101 325 Pa). It was used as a reference condition for physical and chemical properties, and was implicit in the definition of the centigrade scale of temperature, which defined 100В вЊ as the boiling point of water at this pressure.

Symbols, abbreviations, or full names for units of length,ДЄrea, mass, pressure, and other types.The standard atmosphere was originally defined as the pressure exerted by 760 mm of mercury at 0В вЊ and standard gravity ( g n = 9.806 65В m/s 2). You can find metric conversion tables for SI units, as wellДЄs English units, currency, and other data. The SI unit is the pascal (Pa), with 1 millibar = 100 pascals (a hectopascal)Д¬onversion calculator for all types of measurement units. It is not an SI unit of measure, however it is one of the units used in meteorology when describing atmospheric pressure.

This small difference is negligible for most applications outside metrology.ДЄ millibar (mb) is 1/1000th of a bar, a unit for measurement of pressure. The difference between one millimeter of mercury and one torr, as well as between one atmosphere (101.325 kPa) and 760 mmHg (101.3250144354 kPa), is less than one part in seven million (or less than 0.000015%). The relationship between the torr and the millimeter of mercury is: The decimal form of this fraction is approximately 133.322368421. Therefore, 1 Torr is equal toДЎ01325/760 Pa. The torr is defined as 1/760 of one standard atmosphere, while the atmosphere is defined as 101325 pascals. The millimeter of mercury by definition is 133.322387415 Pa (13.5951 g/cm3 Г— 9.80665 m/s2 Г— 1 mm), which is approximated with known accuracies of density of mercury and standard gravity.
