**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.

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

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

*Example: How many kilopounds per square inches are equivalent to 3.77 Millimeters of Mercury?*

As;

1 Millimeters of Mercury = 1.9337E-5 kilopounds per square inches

3.77 Millimeters of Mercury = Y kilopounds per square inches

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

Y equals 3.77 times 1.9337E-5 over 1

(i.e.) Y = 3.77 * 1.9337E-5 / 1 = 7.290049E-5 kilopounds per square inches

Answer is: 7.290049E-5 kilopounds per square inches are equivalent to 3.77 Millimeters of Mercury.
