Conversion Formula
kPa·s = µPa·s × 1.000000000e-9
About Micropascal-seconds
The micropascal-second (µPa·s) equals 10⁻⁶ Pa·s, the viscosity range of dilute gases at ambient conditions. Air at 20 °C has a dynamic viscosity of ≈18.5 µPa·s; helium ≈19.6 µPa·s; hydrogen ≈9.0 µPa·s. Gas turbine and aerodynamics calculations routinely work at this scale. 1 µPa·s = 10⁻⁶ Pa·s = 10⁻³ mPa·s = 10⁻⁵ cP.
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.
