Frequently asked questions
What is the source unit in this conversion?
The source unit is the psi (psi). Pounds per square inch.
What is the destination unit in this conversion?
The destination unit is the torr (Torr). A torr is 1/760 standard atmosphere.
How do I convert psi to torr?
Multiply the psi value by 51.714933. For example, 10 psi × 51.714933 = 517.149326 Torr.
Is the psi to torr 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 psi needs to be compared with, or reported in, torr, such as in engineering specifications, weather readings, tire pressure, or industrial and scientific work.
Can I convert torr back to psi?
Yes. Multiply the torr value by 0.019337 to get psi.

About this conversion
This page converts psi (psi) to torr (Torr) within the pressure converter.
Pounds per square inch. A torr is 1/760 standard atmosphere.
The formula is torr = psi × 51.714933, 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.
