Convert Millipoises to Pounds per inch-second
Convert Millipoises (mP) to Pounds per inch-second (lb/(in·s)) instantly and accurately.
Conversion Formula
lb/(in·s) = mP × 5.599741459e-6
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 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).
