What is millipoise used to measure?

Millipoise is a unit of dynamic viscosity used to quantify low-viscosity fluids with finer resolution than poise or centipoise, commonly for liquids like water, solvents, and printing inks.

When should I use pound-force second per square inch for viscosity?

It is most appropriate for expressing the viscosity of very thick materials such as heavy oils, greases, polymer melts, and adhesives in industrial contexts using US customary units.

Why might the converted values be very small?

Because pound-force second per square inch units correspond to much higher viscosities, converting low millipoise values results in extremely small figures that may be difficult to interpret practically.
