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.
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 Pounds Per Square Inches to Millimeters Of Mercury
Example: How many Millimeters of Mercury are equivalent to 99.77 pounds per square inches?
As;
1 pounds per square inches = 51.71379 Millimeters of Mercury
99.77 pounds per square inches = Y Millimeters of Mercury
Assuming Y is the answer, and by criss-cross principle;
Y equals 99.77 times 51.71379 over 1
(i.e.) Y = 99.77 * 51.71379 / 1 = 5159.4848283 Millimeters of Mercury
Answer is: 5159.4848283 Millimeters of Mercury are equivalent to 99.77 pounds per square inches.
