Frequently Asked Questions
-
What does exastokes measure?
-
Exastokes measure kinematic viscosity, representing dynamic viscosity divided by density, using a very large scale.
-
Why convert exastokes to square millimeter per second?
-
Converting to square millimeter per second expresses extremely large viscosity values in a more practical unit commonly used in fluid dynamics and engineering.
-
Where is square millimeter per second commonly used?
-
Square millimeter per second is widely used in automotive oil specifications, industrial lubrication, and laboratory fluid mechanics.
Key Terminology
-
Exastoke (ESt)
-
A large kinematic viscosity unit equal to 10^18 stokes or 10^14 m²/s, primarily used in theoretical or astrophysical contexts.
-
Square Millimeter per Second (mm²/s)
-
A unit of kinematic viscosity equal to 10^-6 m²/s, commonly used in lubricant characterization and fluid mechanics.
-
Kinematic Viscosity
-
The ratio of dynamic viscosity to density, indicating the diffusion rate of momentum through a fluid.
