What does one pound-force second per square foot measure?

It is a unit of dynamic viscosity in the US customary system describing a fluid's resistance to shear flow, producing one pound-force of shear on a one-square-foot area with a unit velocity gradient.

When should I use pound/foot/second instead of pound-force second/sq. foot?

Pound/foot/second is used in engineering calculations and industrial testing calibrated with imperial units, especially for specifying lubricants or hydraulic fluids.

Can I use this converter for scientific calculations in SI units?

This converter focuses on imperial viscosity units; for SI-based scientific calculations, conversion to pascal-seconds is recommended.
