FAQ

What is the conversion factor from psi to Torr?
1 psi equals 51.71493 Torr. To convert, multiply the value in pounds-force per square inch by 51.71493.
How do I convert 1 psi to Torr?
1 psi = 51.7149 Torr. For any value, multiply by 51.71493.
How do I convert Torr back to psi?
Divide by the same factor — or equivalently, multiply by 0.01933677. So 1 Torr = 0.0193368 psi.
When would I need to convert pound-force per square inch to torr?
Pressure conversions between psi and Torr are common when working with mixed-vendor instrumentation, when piping codes use different units to process datasheets, or when converting field readings into SI for hydraulic calculations.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
