Millimeter Of Mercury (abbreviations: mm Hg, or mmHg): is a manometric unit of pressure, equal to 133.322387415 pascals. It is the extra pressure generated by a column of mercury of one millimeter high.
Atmosphere (abbreviation: atm): is a unit of standard pressure, equal to 101325 Pa, or 1.01325 bar.
How to Convert Millimeters Of Mercury to Atmospheres
Example: How many Atmospheres are equivalent to 42.22 Millimeters of Mercury?
As;
1 Millimeters of Mercury = 0.001316 Atmospheres
42.22 Millimeters of Mercury = Y Atmospheres
Assuming Y is the answer, and by criss-cross principle;
Y equals 42.22 times 0.001316 over 1
(i.e.) Y = 42.22 * 0.001316 / 1 = 0.05556152 Atmospheres
Answer is: 0.05556152 Atmospheres are equivalent to 42.22 Millimeters of Mercury.
