What is the pound-force second per square inch unit used for?

It is an Imperial/US customary unit of dynamic viscosity used to describe thick greases, heavy oils, bitumen, and related industrial fluids by relating shear stress to shear rate.

Why convert pound-force second/sq. inch to poise?

Converting to poise allows engineers and scientists to work with viscosity values in the CGS system, commonly used in labs and international industrial measurements, facilitating better comparison and analysis.

Can this converter be used for low-viscosity fluids?

The pound-force second per square inch unit is tailored for high-viscosity fluids; it may be less precise for low-viscosity fluids, so caution is advised.
