What does pound/foot/second measure?

Pound/foot/second is an Imperial unit of dynamic viscosity representing a fluid's internal resistance to shear flow, defined as pound-force second per square foot.

Why convert pound/foot/second to pound-force second/sq. foot?

The conversion is useful for engineering and fluid characterization when working with different Imperial units or equipment specifications.

Is this conversion used in scientific calculations?

While primarily for Imperial unit consistency, these units are sometimes converted to SI units like pascal-seconds for scientific research.
