Key Terminology
-
Dekastokes (daSt)
-
A unit of kinematic viscosity equal to 10 stokes, used for high viscosity fluids such as lubricating oils and polymer melts.
-
Femtostokes (fSt)
-
A very small CGS-derived unit of kinematic viscosity equal to 10⁻¹⁵ stokes, useful for nanoscale fluid dynamics and microfluidic viscosity measurements.
-
Kinematic Viscosity
-
A measure of how a fluid's momentum diffuses through it, defined as dynamic viscosity divided by density.
