FAQ
What is the conversion factor from Torr to psf?
1 Torr equals 2.784496 psf. To convert, multiply the value in torr by 2.784496.
How do I convert 1 Torr to psf?
1 Torr = 2.7845 psf. For any value, multiply by 2.784496.
How do I convert psf back to Torr?
Divide by the same factor — or equivalently, multiply by 0.3591315. So 1 psf = 0.359131 Torr.
When would I need to convert torr to pound-force per square foot?
Pressure conversions between Torr and psf 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).
