What Is This Tool?
This unit converter allows you to convert kinematic viscosity values from stokes (St), a CGS unit, to dekastokes (daSt), a multiple unit used for higher viscosity fluids. It helps express viscosity measurements conveniently for various industrial and scientific uses.
How to Use This Tool?
-
Enter the viscosity value in stokes (St) into the input field.
-
Select stokes as the source unit and dekastokes as the target unit.
-
Click the convert button to see the result displayed in dekastokes (daSt).
-
Use the converted value to report or analyze high-viscosity fluid properties.
Key Features
-
Convert kinematic viscosity between stokes and dekastokes instantly.
-
User-friendly interface suited for lubrication, rheology, and fluid dynamics applications.
-
Supports viscosity values commonly used in engineering and laboratory settings.
-
Based on established CGS unit definitions for accuracy within specified contexts.
Examples
-
5 Stokes equals 0.5 Dekastokes.
-
20 Stokes equals 2 Dekastokes.
Common Use Cases
-
Specifying kinematic viscosity of heavy lubricating oils and greases in industrial data.
-
Characterizing polymer melts or viscous process streams in rheology.
-
Reporting laboratory viscosity measurements of bitumen, asphalt, and other high-viscosity materials.
-
Calculating fluid behavior in lubrication engineering and petroleum industries.
Tips & Best Practices
-
Ensure consistent temperature control during viscosity measurements for accuracy.
-
Use dekastokes for higher viscosity fluids and stokes or centistokes for lower viscosities.
-
Be cautious when converting between CGS-based and SI units to avoid errors.
-
Double-check unit selections and conversion results for critical applications.
Limitations
-
Stokes and dekastokes are CGS units which may require careful integration with SI units.
-
Dekastokes is appropriate only for relatively large viscosity values; not suited for low viscosity.
-
Viscosity measurements and conversions are sensitive to temperature variations.
Frequently Asked Questions
-
What is the relationship between stokes and dekastokes?
-
One dekastoke is equal to ten stokes, meaning 1 St = 0.1 daSt.
-
When should I use dekastokes instead of stokes?
-
Dekastokes is used for expressing the kinematic viscosity of fluids with higher viscosity like heavy oils and greases.
-
Are these units compatible with SI measurements?
-
Stokes and dekastokes are CGS units, so extra care is needed when integrating with SI units to prevent errors.
Key Terminology
-
Stokes [St]
-
A CGS unit of kinematic viscosity defined as one square centimetre per second (1 St = 1 cm²/s), commonly used to quantify fluid resistance to flow.
-
Dekastokes [daSt]
-
A unit equal to ten stokes (1 daSt = 10 St), used for expressing higher kinematic viscosity values in fluids such as heavy oils and greases.
-
Kinematic Viscosity
-
A measure of a fluid’s resistance to flow under gravity, expressed as the ratio of dynamic viscosity to density.
