FAQ
What is the conversion factor from reyn to Pa·s?
1 reyn equals 6894.757 Pa·s. To convert, multiply the value in reynolds (lbf·s/in²) by 6894.757.
How do I convert 1 reyn to Pa·s?
1 reyn = 6894.76 Pa·s. For any value, multiply by 6894.757.
How do I convert Pa·s back to reyn?
Divide by the same factor — or equivalently, multiply by 0.0001450377. So 1 Pa·s = 0.000145038 reyn.
When would I need to convert reynolds (lbf·s/in²) to pascal-second?
Dynamic viscosity conversions between reyn and Pa·s 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).
