Millimeters of Mercury to Pounds per Square Inch Converter

To convert a measurement in millimeters of mercury to pounds per square inch, multiply the value by 0.019336777459. The conversion factor comes from the relationship between both units and the pascal.

For example, to convert 5 mmHg to pounds per square inch: 5 × 0.019336777459 = 0.096683887297 psi.

A millimeter of mercury (mmHg) is a unit of pressure equal to the pressure exerted by a one-millimeter-high column of mercury, about 133.32 pascals. Derived from early mercury barometers, the mmHg is nearly identical to the torr. It remains the standard unit for blood pressure and other physiological measurements in medicine worldwide.

Common uses of millimeters of mercury include: Blood pressure readings (systolic/diastolic); Intraocular and intracranial pressure; Barometric pressure in medicine; Vacuum and gas-pressure measurement.

Pounds per square inch (psi) is an imperial unit of pressure equal to the force of one pound-force applied to an area of one square inch, or about 6,894.76 pascals. Rooted in the imperial system, psi remains the dominant pressure unit in the United States. It appears on tire gauges, air compressors, and hydraulic equipment throughout North America.

Common uses of pounds per square inch include: Tire pressure in the United States; Air compressors and pneumatic tools; Hydraulic system ratings; Plumbing and water pressure specifications.

Here are some common values converted:
