**Definitions:**

**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 72.53 Millimeters of Mercury?*

As;

1 Millimeters of Mercury = 0.001316 Atmospheres

72.53 Millimeters of Mercury = Y Atmospheres

Assuming Y is the answer, and by criss-cross principle;

Y equals 72.53 times 0.001316 over 1

(i.e.) Y = 72.53 * 0.001316 / 1 = 0.09544948 Atmospheres

Answer is: 0.09544948 Atmospheres are equivalent to 72.53 Millimeters of Mercury.
