1.5.6 Atmospheric pressure Units of atmospheric pressure:N/m2 millibar (=100 N/m2) mm Hg (mercury at 0 °C and at g = 9.80665 ms−2) Note: The “torr” as used in vacuum work is 1/760 standard atmospheric pressure but is not recognised for measuring barometric pressure. 1 mmHg =...

Convert Atmosphere Atm Standard to Millitorrs (atm in mTorr). Atmosphere Atm Standard and Millitorrs both are the units of PRESSURE. See the charts and tables conversion here!
The torr (symbol: Torr) or millimetre of mercury (mmHg) is a non-SI unit of pressure. It is the atmospheric pressure that supports a column of mercury 1 millimetre high. The unit is named after Evangelista Torricelli, Italian physicist and mathematician, for his discovery of the principle ...
Pressure: 1 atm (101.325 kilopascal or 760 Torr). This definition is now discontinued. Nonetheless, these conditions are still commonly used to define the volume (V) termnormal cubic meter. Since 1982, IUPAC has applied a more stringent definition of STP: ...
The vapor pressure of ozone has been measured at liquid argon temperatures. At the normal boiling point of argon (−185.9°C) an ozone pressure of 4.05 × 10−2 Torr was obtained with an accuracy of ±1.5%. Increases and decreases in liquid argon temperatures raised and lowered the ...
Atmospheric pressure in inHg units What does one atmospheric pressure equal in inches of mercury? The standard constant value used for atmospheric pressure at sea level is 1 atm (standard atmosphere) which equals 101325 pascals in SI units, and is equivalent to 29.9213inches of mercury. ...
Answer and Explanation:1 The equation for Boyle's Law is: {eq}\rm P_1V_1=P_2V_2 {/eq} where: {eq}\rm P_1 {/eq} is the initial pressure in atm {eq}\rm V_1 {/eq} is the...

The standard pressure is equal to: 1 atm = 760 Torr = 760 mm Hg = 101.35 kPa. Easy to remember –the standard pressure is equal to 1 atmosphere. 1 mol of ideal gas in these conditions has a volume of 22.4 liters. What are the STP conditions used for? STP conditions are used to ...
