Air pressure can be expressed using different units of measure, such as atmospheres (atm), kilopascals (kPa), kilogram per square meter (kg/m2), millibars (mb), millimeters of mercury (mmHg), and pounds-force per square inch (psi). The conversion to atm units depends on what units your original value are in.To see how the different units compare, 1 atm is equal to:760 torr101.3 kPa (kilopascals)0.1013 MPa (megapascals)101325 Pa (pascals)760 mmHg (millimeters of mercury)29.92 inHg (inches of mercury)1.013 bars1013 mbar (millibars)14.7 psi (pounds-force per square inch)2116 lbf/ft^2 (pounds-force per square foot)The standard measure of pressure (i.e the SI unit) is the pascal, but the kilopascal (kPa) is usually used for measuring atmospheric pressure. As such, here is the formula used to convert atm to kpa:Pressure in atm = kPa value / (101.325 kPa/atm)For example, to convert the pressure of 99.5 kPa into atm: = 99.5 kPa / (101.325 kPa)= 0.98198865 atm
mm Hg/760
-24.43 inches of mercury.
PressureMillimeters of mercury (written as mm Hg) are a measure of pressure. Another standard measure of pressure is called an atmosphere (ATM). 1 mm Hg = 0.00131578947 ATMHere are the conversions between other standard measures of pressure: 1 ATM = 14.6959488 pounds per square inch (PSI)1 ATM = 29.9246899 inches of mercury (in Hg)1 ATM = 760 mm mercury (mm Hg)1 ATM = 760 torr1 ATM = 101 325 pascals1 ATM = 1.01325 barblood pressure Kara a seventh grade student :D
24.34 inches of mercury = 618.2 Torr
1 ATM equates to ~29.921 inches of mercury.
Multiply inches of mercury by 0.033421057 to get atmospheres.
18,920 mm of mercury at 24.9 ATM
Using dimensional analysis (unit analysis):5 pa * [(1 atm) / (101325 pa)] * [(760 mm Hg) / (1 atm)] * [ (1 inch) / (25.4 mm)] = 0.00148 inches Hg

0.1 atm equals 76 mm of Mercury pressure.
1 standard atmosphere is 760 millimeter of mercury. 2.25 ATM is 1710 mmHg.
Mercury is 3 inches
It is the standard atmospheric pressure at sea level. It is equal to 1 atm.
The pressure is one atmosphere (atm), equal to 1.01325 bar (1013.25 millibars or 101.325 kilopascals). This is about 14.7 psi (pounds per square inch) or 29.9213 inches (760 mm) of Mercury.
If the atmospheric pressure is 29.4 inches of mercury the corresponding inches of mercury is: 880.
Inches of mercury x 0.4912 = psi
