About Slugs per foot-second
The slug per foot-second (slug/(ft·s)) equals 1 lbf·s/ft² ≈ 47.880 Pa·s, the coherent FPS viscosity unit where force is in pound-force. It is used in US aerospace and hydraulic engineering when working with the slug as the unit of mass. Water at 20 °C has a viscosity of ≈2.09×10⁻⁵ slug/(ft·s); hydraulic fluid MIL-PRF-5606 is ≈3×10⁻⁴ slug/(ft·s) at 100 °F. 1 slug/(ft·s) ≈ 47.880 Pa·s.
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.
