A unit of kinematic viscosity equal to 10^-18 stokes, used to express extremely small viscosity values in nanoscale and theoretical fluid studies.
-
Kinematic Viscosity
-
The ratio of dynamic viscosity to density, representing how momentum diffuses through a fluid.
-
Stokes (St)
-
A unit of kinematic viscosity equal to 1 cm^2/s, forming the basis for defining attostokes.
