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 0.0193368. For example, 10 Torr × 0.0193368 = 0.193368 psi.
Is the Torr to PSI conversion exact?
Yes. Both units belong to the same engineering measurement family (pressure and mechanical stress), so the ratio between them is a fixed, defined value 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, scientific, or industrial calculations.
Can I convert PSI back to Torr?
Yes. Multiply the PSI value by 51.7149 to get Torr.

About this conversion
This page converts Torr (Torr) to PSI (psi) within the engineering converter.
A torr is 1/760 standard atmosphere. Pounds per square inch.
The formula is psi = Torr × 0.0193368, based on each unit's fixed relationship to the pressure and mechanical stress base unit.
The conversion is exact, since it relies on a fixed numerical ratio between the two units rather than a measured or approximate value.
