Frequently asked questions
What is the source unit in this conversion?
The source unit is the torr (Torr). A torr is 1/760 standard atmosphere.
What is the destination unit in this conversion?
The destination unit is the psi (psi). Pounds per square inch.
How do I convert torr to psi?
Multiply the torr value by 0.019337. For example, 10 Torr × 0.019337 = 0.193368 psi.
Is the torr to psi conversion exact?
Yes. Both units are defined as fixed multiples of the pascal, the SI-derived unit of pressure, so the conversion factor follows directly from those exact definitions rather than a measured approximation.
Where is this conversion commonly used?
It's used whenever a value expressed in torr needs to be compared with, or reported in, psi, such as in engineering specifications, weather readings, tire pressure, or industrial and scientific work.
Can I convert psi back to torr?
Yes. Multiply the psi value by 51.714933 to get torr.

About this conversion
This page converts torr (Torr) to psi (psi) within the pressure converter.
A torr is 1/760 standard atmosphere. Pounds per square inch.
The formula is psi = torr × 0.019337, based on each unit's fixed relationship to the pascal, the pressure converter's base unit.
The conversion is exact, since both units are tied to the pascal by a fixed numerical ratio rather than a measured or approximate value.
