Conversion Formula
cP = µPa·s × 0.001
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 Centipoises
The centipoise (cP) equals 10⁻³ Pa·s, numerically equal to 1 mPa·s. It remains the most widely used practical unit in industry because water at 20 °C has a viscosity of almost exactly 1 cP. Process engineers, petroleum analysts, and food technologists all specify viscosity in cP. Motor oil SAE 10W has a cold-viscosity limit of ≈3 500 cP at -25 °C. 1 cP = 10⁻³ Pa·s = 10⁻² P.
