Convert Pound-force seconds per square inch (lbf·s/in²) to Millipascal-seconds (mPa·s) instantly and accurately.
Conversion Formula
mPa·s = lbf·s/in² × 6894757.293
About Pound-force seconds per square inch
The pound-force second per square inch (lbf·s/in², reyn) equals 144 × 47.880 ≈ 6 894.8 Pa·s. Informally called the "reyn" (after Osborne Reynolds), it is used in US tribology and bearing-design engineering, where oil-film viscosity in heavily loaded contacts is stated in reyn. Turbine bearing oils at operating temperature range 0.5-3 × 10⁻⁶ reyn. 1 reyn ≈ 6 894.8 Pa·s.
About Millipascal-seconds
The millipascal-second (mPa·s) equals 10⁻³ Pa·s and is numerically identical to the centipoise (cP). It is the standard unit in modern SI-based fluid-property tables. Water at 20 °C is ≈1.002 mPa·s; blood plasma ≈1.2 mPa·s; light mineral oil 20-60 mPa·s. 1 mPa·s = 10⁻³ Pa·s = 1 cP.
