What does pound-force second per square inch measure?

It measures dynamic (absolute) viscosity relating shear stress to shear rate in the Imperial/US customary system.

When should I use gigapoise as a unit?

Gigapoise is used for very viscous substances such as cured polymers, bitumen, or geological materials requiring large-scale viscosity values.

Why is it important to convert between these two units?

Converting helps translate viscosity data between US customary engineering units and CGS units suited for specific scientific and industrial applications.

Is this conversion applicable to all viscosity measurements?

No, it is most relevant for very thick, viscous materials or legacy data where these units are used.
