Convert Kilopascal-seconds to Pound-force seconds per square inch
Convert Kilopascal-seconds (kPa·s) to Pound-force seconds per square inch (lbf·s/in²) instantly and accurately.
Conversion Formula
lbf·s/in² = kPa·s × 0.1450377377
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.
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.
