What does pound-force second per square foot measure?

It measures dynamic viscosity in the Imperial system, indicating a fluid's resistance to shear flow.

Dekapoise is a cgs-based unit of dynamic viscosity equal to 10 poise, equivalent to 1 pascal-second in SI units.

Why convert between these two units?

To translate viscosity measurements from Imperial units into a cgs unit commonly used in rheology and fluid mechanics, enabling easier comparison and analysis.
