Frequently Asked Questions
-
What does microstokes (µSt) measure?
-
Microstokes measure kinematic viscosity, quantifying momentum diffusivity in fluids, represented as one millionth of a stoke.
-
Why convert microstokes to attostokes?
-
Converting to attostokes enables expressing viscosity at much finer scales, useful in nanoscale research and molecular-level fluid studies.
-
Are attostokes commonly used in everyday measurements?
-
No, attostokes are primarily used in advanced theoretical or nanoscale fluid dynamics research due to their extremely small magnitude.
Key Terminology
-
Microstokes [µSt]
-
A unit of kinematic viscosity equal to one millionth of a stoke, representing momentum diffusivity at a microscopic fluid scale.
-
Attostokes [aSt]
-
An extremely small unit of kinematic viscosity equal to 10^-18 stokes, used to describe very low viscosity values in nanoscale fluid studies.
-
Kinematic Viscosity
-
The ratio of a fluid’s dynamic viscosity to its density, quantifying how momentum diffusivity occurs in fluid flow.
