About Pound per foot-second (lb/(ft·s))
An imperial dynamic-viscosity unit (using pound-mass). Primarily encountered in US petroleum engineering, legacy ASME fluid-mechanics textbooks, and HVAC calculations where engineers prefer consistent US customary units throughout. 1 lb/(ft·s) ≈ 1.488 Pa·s. Most modern US engineering has migrated to centipoise or Pa·s, so this unit is most useful for interpreting older specifications and technical literature.
About Pascal-second (Pa·s)
The SI unit of dynamic (absolute) viscosity — the ratio of shear stress to velocity gradient in a flowing fluid. Pa·s is the universal unit in fluid mechanics textbooks, CFD simulations, and lubricant engineering. Water at 20°C has a dynamic viscosity of about 0.001 Pa·s; SAE 30 motor oil is about 0.1 Pa·s; honey is around 10 Pa·s. Rheology, tribology, and polymer melt flow all use Pa·s in scientific publications.
