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 Poise (P)
The CGS unit of dynamic viscosity, equal to 0.1 Pa·s. Named after French physician Jean Poiseuille, who studied blood flow in the 19th century. Although superseded by Pa·s in modern SI usage, poise still appears in older fluid-dynamics literature, geological rheology (rock/magma viscosities span 10¹⁰ to 10²¹ P), and some glass/polymer manufacturing tables.
