What does pound-force second per square foot measure?

It measures dynamic (absolute) viscosity quantifying a fluid's resistance to shear in the Imperial/US customary system.

Why convert to kilopoise?

Kilopoise is used to report very high viscosities and is common in rheology and materials processing in a cgs-based unit system.

Can this converter be used for all fluid types?

It is suited for high-viscosity fluids like heavy oils, greases, tar, polymer melts, and concentrated suspensions.

Key Terminology

Pound-force second per square foot (lbf·s/ft²): An Imperial unit of dynamic viscosity quantifying fluid resistance to shear, defined as one pound-force of shear on a one-square-foot area per unit velocity gradient.
Kilopoise (kP): A non-SI unit of dynamic viscosity equal to 1000 poise, where 1 poise equals 0.1 pascal-second.
Dynamic viscosity: A measure of a fluid’s internal resistance to flow by shear stress per unit velocity gradient.
