Frequently Asked Questions
-
What does stokes measure?
-
Stokes measures kinematic viscosity, describing a fluid's resistance to flow as the ratio of dynamic viscosity to density, using a CGS unit.
-
Why use attostokes for viscosity?
-
Attostokes are used to express extremely low kinematic viscosities typically found in nanoscale, molecular, or theoretical fluid dynamics research.
-
How many attostokes are in one stokes?
-
One stokes equals one quintillion attostokes, that is 1 St = 1,000,000,000,000,000,000 aSt.
Key Terminology
-
Stokes [St]
-
A CGS unit of kinematic viscosity defined as one square centimetre per second, used to measure fluid resistance to flow.
-
Attostokes [aSt]
-
A unit of kinematic viscosity equal to 10^-18 stokes, applied for very small viscosity values in nanoscale fluids and simulations.
-
Kinematic viscosity
-
The ratio of dynamic viscosity to density, representing how momentum is transported within a fluid.
