What does pound-force second per square foot measure?

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

When should I use femtopoise units?

Femtopoise units are ideal for expressing extremely small viscosity values, such as those in nanoscale simulations or rarefied-gas research.

Are there any challenges when converting between these units?

Yes, because of the huge numerical conversion factor involved, rounding errors might occur, and high-precision calculation may be necessary.
