What does pound-force second per square foot measure?

It measures dynamic viscosity in the Imperial system, representing fluid resistance to shear flow per unit area and velocity gradient.

When is attopoise used?

Attopoise is used to express extremely small viscosities typical in molecular, nanoscale, and ultracold gas studies.

Why is the conversion factor so large?

Because pound-force second/sq. foot measures macroscopic viscosities and attopoise measures atomic-scale viscosities, resulting in a huge scale difference.
