µPa·s = Pa·s × 1000000
About Pascal-seconds
The pascal-second (Pa·s) is the SI coherent unit of dynamic viscosity, equal to 1 kg/(m·s) = 1 N·s/m². Honey at 25 °C is ≈2-10 Pa·s; glycerol ≈1.4 Pa·s; bitumen 10⁴-10⁸ Pa·s. It replaced the poise in SI usage and is the standard unit in research and simulation software (CFD, process simulators). 1 Pa·s = 10 P = 1 000 cP.
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.
