What does poundal second per square foot measure?

It measures dynamic (absolute) viscosity, representing a force of one poundal applied over one second on a one-square-foot area, quantifying fluid resistance to shear flow.

When should I use pound-force second per square foot?

Use it when working with US customary engineering data involving viscosity, such as in petroleum processing, lubrication, and pump design.

Why is converting between these units important?

Conversions are essential to align viscosity measurements across different imperial units, enabling accurate fluid dynamics analyses and comparison of legacy and modern data.
