**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.

**Bar** (abbreviation: **bar**): is a metric (still not approved by the International System of Units, SI) unit of pressure. It is exactly equal to 100,000 Pa and slightly lower than the current average atmospheric pressure on Earth, at sea level.

## How to Convert Millimeters Of Mercury to Bars

*Example: How many Bars are equivalent to 84.46 Millimeters of Mercury?*

As;

1 Millimeters of Mercury = 0.001333 Bars

84.46 Millimeters of Mercury = Y Bars

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

Y equals 84.46 times 0.001333 over 1

(i.e.) Y = 84.46 * 0.001333 / 1 = 0.11258518 Bars

Answer is: 0.11258518 Bars are equivalent to 84.46 Millimeters of Mercury.
