Convert Pounds per inch-second (lb/(in·s)) to Kilopascal-seconds (kPa·s) instantly and accurately.
Conversion Formula
kPa·s = lb/(in·s) × 0.01785796732
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 Kilopascal-seconds
The kilopascal-second (kPa·s) equals 1 000 Pa·s, used for highly viscous materials such as bitumen binders, polymer melts, and pitch at processing temperatures. Bitumen (road asphalt) at 60 °C has a dynamic viscosity of 100-10 000 Pa·s = 0.1-10 kPa·s; hot-melt adhesives at application temperature are 10-100 kPa·s. 1 kPa·s = 1 000 Pa·s = 10 000 P.
