About Pounds per inch-second
The pound per inch-second (lb/(in·s)) equals 0.45359237/0.0254 ≈ 17.858 Pa·s, used in plastics extrusion and rubber compounding industries where inch-based dimensions are combined with mass-based flow analysis. Polymer melt viscosities at processing temperatures are sometimes quoted in lb/(in·s) in older US extrusion equipment manuals. 1 lb/(in·s) ≈ 17.858 Pa·s = 12 lb/(ft·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.
