FAQ

What is the conversion factor from psi to dyn/cm²?
1 psi equals 68947.57 dyn/cm². To convert, multiply the value in pounds-force per square inch by 68947.57.
How do I convert 1 psi to dyn/cm²?
1 psi = 68947.6 dyn/cm². For any value, multiply by 68947.57.
How do I convert dyn/cm² back to psi?
Divide by the same factor — or equivalently, multiply by 1.450377e-5. So 1 dyn/cm² = 1.45038e-5 psi.
When would I need to convert pound-force per square inch to dyne per square centimetre?
Pressure conversions between psi and dyn/cm² 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).
