What Is This Tool?
This converter allows you to translate kinematic viscosity values from attostokes (aSt), used to express extremely small viscosity levels, into square centimeters per second (cm²/s), the commonly used CGS unit for fluid momentum diffusivity.
How to Use This Tool?
-
Enter the viscosity value in attostokes (aSt) into the input field.
-
Select attostokes as the source unit and square centimeter/second as the target unit.
-
Click the convert button to get the equivalent value in cm²/s.
Key Features
-
Supports conversion between attostokes and square centimeter/second units.
-
Utilizes the exact conversion rate where 1 aSt equals 1 × 10⁻¹⁸ cm²/s.
-
Browser-based and easy to use for fluid mechanics and nanoscale research applications.
Examples
-
5 aSt converts to 5 × 10⁻¹⁸ cm²/s
-
1 aSt converts to 1 × 10⁻¹⁸ cm²/s
Common Use Cases
-
Interpreting extremely low kinematic viscosity results from molecular dynamics or atomistic simulations.
-
Describing momentum transport in nanoscale lubrication films and micro/nanofluidic research.
-
Converting theoretical viscosity values to standard CGS units for engineering and fluid mechanics experiments.
Tips & Best Practices
-
Ensure correct selection of source and target units before conversion.
-
Understand the physical context since attostokes values represent very small and sometimes theoretical viscosities.
-
Use the converted values to facilitate comparisons with standard engineering and experimental data.
Limitations
-
Attostokes values represent extremely small viscosity measures that might exceed typical measurement precision.
-
Applying these conversions in macroscopic experiments requires caution due to physical and measurement constraints.
Frequently Asked Questions

Key Terminology
-
Attostokes [aSt]
-
A unit of kinematic viscosity equal to 10⁻¹⁸ stokes, representing extremely low momentum diffusivity in fluids.
-
Square Centimeter/Second (cm²/s)
-
The CGS unit for kinematic viscosity measuring fluid momentum diffusivity as the ratio of dynamic viscosity to density.
-
Kinematic Viscosity
-
The momentum diffusivity of a fluid, defined as dynamic viscosity divided by fluid density.
