What Is This Tool?
This online converter allows you to easily transform kinematic viscosity values from square inch per second, an imperial unit, to exastokes, a rarely used but extremely large viscosity unit. It supports contexts ranging from engineering using US customary units to theoretical and astrophysical studies.
How to Use This Tool?
-
Enter the kinematic viscosity value in square inch per second (in^2/s)
-
Choose square inch/second as the input unit and exastokes (ESt) as the output unit

-
10 in^2/s converts to 6.4516 × 10^-17 ESt
Common Use Cases
-
Specifying kinematic viscosity of lubricating oils and hydraulic fluids in systems using imperial units
-
Providing input for fluid-flow calculations and computational fluid dynamics models in US customary unit contexts
-
Quality control reports of fluid viscosities in petroleum and refinery industries using imperial measurements
-
Theoretical or pedagogical examples demonstrating large prefix conversions of kinematic viscosity units
-
Astrophysical or planetary science scaling discussions, such as mantle convection or accretion flow viscosity models
Tips & Best Practices
-
Double-check the unit selections to ensure accurate conversion between in^2/s and ESt
-
Use this conversion primarily for theoretical, educational, or large-scale scientific contexts
-
Avoid using the exastoke unit for everyday industrial or engineering measurements due to its impractical magnitude
-
Understand the physical context to choose appropriate units for your viscosity data
Limitations
-
Exastoke is an extremely large unit rarely applied outside theoretical or astrophysical scenarios
-
It is not practical for common lubrication or fluid dynamics viscosity measurements
-
The conversion serves mainly pedagogical or conceptual purposes rather than everyday engineering use
Frequently Asked Questions
-
What is the square inch per second unit used for?
-
Square inch per second is an imperial unit of kinematic viscosity often used to specify lubricating oils and hydraulic fluids in systems employing US customary units.
-
Why is the exastoke unit rarely used?
-
The exastoke is extremely large, making it impractical for typical industrial or engineering applications and mainly relevant for theoretical or astrophysical contexts.
-
How do I convert square inch per second to exastokes?
-
You multiply the value in square inch/second by 6.4516 × 10^-18 to obtain the equivalent in exastokes.
Key Terminology
-
Square inch/second [in^2/s]
-
An imperial unit of kinematic viscosity defining one square inch of area moved per second, used primarily in US customary fluid-flow applications.
-
Exastoke [ESt]
-
A very large unit of kinematic viscosity equal to 10^18 stokes, used rarely for theoretical or scientific scaling of viscosity values.
-
Kinematic viscosity
-
The ratio of dynamic viscosity to density, representing a fluid's internal resistance to flow under gravity, measured as area per unit time.
