Formula
Formula
reyn = mPa·s × 1.450377e-7
Multiply any value in millipascal-seconds by 1.450377e-7 to obtain the value in reynolds (lbf·s/in²).
Worked example
Convert 1.00000e+6 mPa·s to reyn.
- 01Start with 1.00000e+6 mPa·s.
- 02Multiply by the conversion factor: 1.00000e+6 × 1.450377e-7 = 0.145038 reyn.
Result1.00000e+6 mPa·s = 0.145038 reyn

FAQ
What is the conversion factor from mPa·s to reyn?
1 mPa·s equals 1.450377e-7 reyn. To convert, multiply the value in millipascal-seconds by 1.450377e-7.
How do I convert 1 mPa·s to reyn?
1 mPa·s = 1.45038e-7 reyn. For any value, multiply by 1.450377e-7.
How do I convert reyn back to mPa·s?
Divide by the same factor — or equivalently, multiply by 6894757. So 1 reyn = 6.89476e+6 mPa·s.
When would I need to convert millipascal-second to reynolds (lbf·s/in²)?
Dynamic viscosity conversions between mPa·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).
