What is a dekastoke (daSt)?

A dekastoke is a unit of kinematic viscosity equal to 10 stokes, commonly used to measure high-viscosity fluids like heavy oils.

When should I use petastokes (PSt)?

Petastokes are used for estimating extremely large viscosity values in geophysics or planetary science, but are uncommon in everyday engineering.

How do I convert dekastokes to petastokes?

Multiply the value in dekastokes by 1e-14 to get the equivalent value in petastokes.
