**Definitions:**

**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.

**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.

## How to Convert Bars to Millimeters Of Mercury

*Example: How many Millimeters of Mercury are equivalent to 9.65 Bars?*

As;

1 Bars = 750.0188 Millimeters of Mercury

9.65 Bars = Y Millimeters of Mercury

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

Y equals 9.65 times 750.0188 over 1

(i.e.) Y = 9.65 * 750.0188 / 1 = 7237.68142 Millimeters of Mercury

Answer is: 7237.68142 Millimeters of Mercury are equivalent to 9.65 Bars.
