What does the square meter per second unit measure?

Square meter per second (m²/s) measures kinematic viscosity, defining how momentum diffuses through a fluid by dividing dynamic viscosity by fluid density.

When is petastokes [PSt] used?

Petastokes are used mainly for extremely large-scale viscosity values in geophysical or planetary flows and for educational demonstrations to illustrate unit scale differences.

Why is petastokes rarely used in engineering?

Because petastokes represent extremely large values, they are impractical for typical engineering fluid viscosity measurements which commonly use the SI unit m²/s.
