Torr to Pounds per Square Inch Converter

To convert a measurement in torr to pounds per square inch, multiply the value by 0.019336774705. The conversion factor comes from the relationship between both units and the pascal.

For example, to convert 5 Torr to pounds per square inch: 5 × 0.019336774705 = 0.096683873523 psi.

A torr is a unit of pressure defined as 1/760 of a standard atmosphere, approximately equal to one millimeter of mercury (about 133.32 pascals). Named after Evangelista Torricelli, inventor of the barometer, the torr is used mainly in vacuum technology and laboratory work where low pressures are measured against a mercury column.

Common uses of torr include: Vacuum system measurements; Laboratory and analytical instruments; Semiconductor process chambers; Physiology and respiratory gas pressures.

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.
