About psi and torr

The Conversion Formula

To convert psi to torr, multiply the value by the conversion factor: 1 psi = 51.7151 Torr. For a worked example, suppose you need to convert 25 psi to torr: 25 × 51.7151 = 1292.88 Torr. To convert in the opposite direction, divide by 51.7151, or equivalently multiply by 0.0193367.

About psi

PSI stands for 'Pounds per Square Inch'. It is the standard unit for pressure in the United States. It measures how many pounds of force are pressing on every square inch of surface. It is the unit every American driver looks for when filling their tires. psi are commonly used in Tire pressure (US), Blood pressure (rarely), Scuba tanks (US), and Industrial pumps, Paintball tanks.

A standard car tire is inflated to 30-35 psi.

About torr

The Torr is named after Evangelista Torricelli, the inventor of the barometer. It is defined as exactly 1/760 of a standard atmosphere. For almost all practical purposes, 1 Torr equals 1 mmHg. It is primarily used in high-vacuum physics and engineering. torr are commonly used in High vacuum systems, Mass spectrometry, Thin-film manufacturing, and Physics research.

Outer space is a near-perfect vacuum (0 Torr).

When Would You Convert psi to torr?

Converting between psi and torr is one of the most common pressure conversions. You might need this conversion when working with international specifications, following instructions written for a different measurement system, or comparing values across different standards. Having the conversion factor (1 psi = 51.7151 Torr) memorized or bookmarked can save time in professional and everyday contexts alike.
