**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.

**Pound Per Square Inch** (abbreviations: **psi, or lb/in2**): is a unit of pressure or of stress based on avoirdupois units. It is the pressure resulting from a force of one pound-force applied to an area of one square inch.

## How to Convert Millimeters Of Mercury to Pounds Per Square Inches

*Example: How many pounds per square inches are equivalent to 95.07 Millimeters of Mercury?*

As;

1 Millimeters of Mercury = 0.019337 pounds per square inches

95.07 Millimeters of Mercury = Y pounds per square inches

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

Y equals 95.07 times 0.019337 over 1

(i.e.) Y = 95.07 * 0.019337 / 1 = 1.83836859 pounds per square inches

Answer is: 1.83836859 pounds per square inches are equivalent to 95.07 Millimeters of Mercury.
