Convert torr to psi

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.

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.

How to Convert Torr to Pound per square inch

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

1 Torr = 0.019337 psi

1 psi = 51.714933 Torr

Formula: value × 0.0193367747046

Example: 15 Torr = 0.290052 psi

1. Start with the pressure value in Torr.
2. Use 133.3223684211 Pa for each Torr.
3. Use 6894.757293168 Pa for each psi.
4. Multiply Torr by about 0.0193367747 to get psi.

Precision note: Use 1 Torr = 0.0193367747 psi. Keep precision when converting laboratory or vacuum data.
