Pounds per Square Inch to Torr Converter

To convert a measurement in pounds per square inch to torr, multiply the value by 51.714933. The conversion factor comes from the relationship between both units and the pascal.

For example, to convert 5 psi to torr: 5 × 51.714933 = 258.574663 Torr.

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.

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.

Here are some common values converted:

1 psi = 51.714933 Torr 5 psi = 258.574663 Torr 10 psi = 517.149326 Torr 50 psi = 2,585.7466 Torr 100 psi = 5,171.4933 Torr
