Formula
Formula
reyn = Pa·s × 0.0001450377
Multiply any value in pascal-seconds by 0.0001450377 to obtain the value in reynolds (lbf·s/in²).
Worked example
Convert 1000 Pa·s to reyn.
- 01Start with 1000 Pa·s.

FAQ
What is the conversion factor from Pa·s to reyn?
1 Pa·s equals 0.0001450377 reyn. To convert, multiply the value in pascal-seconds by 0.0001450377.
How do I convert 1 Pa·s to reyn?
1 Pa·s = 0.000145038 reyn. For any value, multiply by 0.0001450377.
How do I convert reyn back to Pa·s?
Divide by the same factor — or equivalently, multiply by 6894.757. So 1 reyn = 6894.76 Pa·s.
When would I need to convert pascal-second to reynolds (lbf·s/in²)?
Dynamic viscosity conversions between Pa·s and reyn are common in fluid characterisation, pump and control valve sizing, pipeline pressure-drop calculations, and lubrication engineering. Centipoise (cP) and mPa·s are the most widely used units in process datasheets; Pa·s is required for most simulation tools.
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).
