FAQ

What is the conversion factor from Pa to psi?
1 Pa equals 0.0001450377 psi. To convert, multiply the value in pascals by 0.0001450377.
How do I convert 1 Pa to psi?
1 Pa = 0.000145038 psi. For any value, multiply by 0.0001450377.
How do I convert psi back to Pa?
Divide by the same factor — or equivalently, multiply by 6894.757. So 1 psi = 6894.76 Pa.
When would I need to convert pascal to pound-force per square inch?
Pressure conversions between Pa and psi 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).
