Frequently Asked Questions
-
What does attostokes measure?
-
Attostokes measure kinematic viscosity at an extremely small scale, representing momentum diffusivity in very low viscosity fluids, useful in theoretical and nanoscale fluid studies.
-
Why convert attostokes to microstokes?
-
Converting attostokes to microstokes expresses very low viscosities in larger, more practical units, facilitating clearer analysis in microfluidics and nanoscale research.
-
Are conversions exact?
-
Conversions use defined rates, but extremely small values mean numerical precision can be a limiting factor, so care is needed when interpreting results.
Key Terminology
-
Attostokes (aSt)
-
A unit of kinematic viscosity equal to 10^-18 stokes, used to describe extremely low viscosity values, especially at molecular and nanoscale levels.
-
Microstokes (µSt)
-
A unit of kinematic viscosity equal to 10^-6 stokes, commonly used in microfluidics and aerodynamic experiments to quantify small momentum diffusivity.
-
Kinematic Viscosity
-
The ratio of a fluid's dynamic viscosity to its density, measuring how momentum is transported within the fluid.
