About Pounds per foot-second
The pound per foot-second (lb/(ft·s)) equals 0.45359237/0.3048 ≈ 1.4882 Pa·s, the absolute viscosity unit in the foot-pound-second (FPS) system. It appears in legacy US chemical engineering textbooks and fluid mechanics problems stated in USC units. A heavy fuel oil at 50 °C with viscosity 0.050 Pa·s = 0.0336 lb/(ft·s). 1 lb/(ft·s) ≈ 1.4882 Pa·s = 14.882 P.
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.
