Torr to Psi Converter
How to convert torr to psi
psi = torr ÷ 51.7149326
To convert torr to psi, divide the number of torr by 51.7149326.
1 Torr = 0.0193367747 psi
Examples
- One standard atmosphere: 760 Torr ÷ 51.7149326 = 14.6959488 psi
- 1 Torr ÷ 51.7149326 = 0.0193367747 psi
Good to know
The torr is defined as 101,325/760 Pa. It differs from the millimeter of mercury (133.322387415 Pa) by less than one part in seven million.
Psi means pounds-force per square inch (lbf/in²). Gauge readings (psig) are measured relative to atmospheric pressure, absolute readings (psia) relative to a vacuum; the conversion factor is the same for both.

Unit definitions
- Torr
- A torr is exactly 1/760 of a standard atmosphere, about 133.322 pascals. It is used mainly for vacuum measurements.
- Psi
- Psi is one pound-force per square inch, about 6894.757 pascals. It is the everyday pressure unit in the United States, used for tires, compressors and plumbing.
