What does square millimeter/second measure?

Square millimeter/second is a unit of kinematic viscosity indicating how momentum diffuses through a fluid, used widely in engineering and laboratory fluid studies.

Why use petastokes for kinematic viscosity?

Petastokes represent enormously large viscosity values, suitable for rare geophysical scale estimates or teaching unit magnitude differences, rather than everyday engineering.

Is petastokes commonly applied in engineering?

No, petastokes are generally not practical for engineering as they deal with very large values; typical viscosities are expressed in mm²/s or standard SI units.
