Pound per square inch

Pound per square inch is a pressure unit based on one pound-force applied over one square inch.

Psi became common in US customary pressure measurement and remains widely used on gauges and equipment labels.

psi is used for tires, compressors, hydraulics, pneumatics, pressure gauges, industrial equipment, and service documentation.

Torr

A torr is a pressure unit defined as 1/760 of a standard atmosphere.

Torr is named after Evangelista Torricelli and remains associated with mercury-column and vacuum pressure measurement.

Torr is used in vacuum systems, laboratories, physics, chemistry, pressure gauges, and low-pressure process documentation.

How to Convert Pound per square inch to Torr

Mathematically, torr (Torr) = pound per square inch (psi) converted with the formula below.

1 psi = 51.714933 Torr

1 Torr = 0.019337 psi

Formula: value × 51.7149325715

Example: 15 psi = 775.723989 Torr

  1. Start with the pressure value in psi.
  2. Use 6894.757293168 Pa for each psi.
  3. Use 133.3223684211 Pa for each Torr.
  4. Multiply psi by about 51.71493257 to get Torr.

Precision note: Use 1 psi = 51.71493257 Torr. Preserve precision for lab comparisons, calibration, and low-pressure work.
