Convert Millipoises to Pound-force seconds per square inch
Convert Millipoises (mP) to Pound-force seconds per square inch (lbf·s/in²) instantly and accurately.
Conversion Formula
lbf·s/in² = mP × 1.450377377e-8
About Millipoises
The millipoise (mP) equals 10⁻⁴ Pa·s, an intermediate CGS unit between the micropascal-second gas range and the centipoise liquid range. It is occasionally used in older European scientific literature and in the textile industry for sizing-solution viscosity. Air at 20 °C is ≈ 0.185 mP; a 0.5% polymer solution might read 5-20 mP. 1 mP = 10⁻⁴ Pa·s = 0.1 cP.
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.
