What Is This Tool?
This converter allows users to transform kinematic viscosity measurements from centistokes (cSt), a commonly used unit in lubrication engineering, to square meter per second (m²/s), the SI standard unit. It supports engineers and scientists in obtaining standardized viscosity values for fluid flow analysis and modeling.

-
Supports accurate unit recognition based on engineering and hydraulic viscosity contexts.
Examples
-
10 cSt = 10 × 0.000001 = 0.00001 m²/s
-
500 cSt = 500 × 0.000001 = 0.0005 m²/s
Common Use Cases
-
Specifying motor oil and lubricant viscosities at standard temperatures (e.g., 40 °C and 100 °C).
-
Selecting appropriate hydraulic fluids and lubricants for bearings and gearboxes based on flow behavior.
-
Performing Reynolds number calculations and studying flow regimes in lubrication and fluid process engineering.
-
Modeling boundary layers and turbulence in aerodynamics and computational fluid dynamics.
-
Converting lubricant viscosities to SI units for consistent engineering and scientific analysis.
Tips & Best Practices
-
Ensure consistent temperature and pressure conditions when using converted kinematic viscosity values.
-
Use precise measurements of dynamic viscosity and fluid density to improve conversion reliability.
-
When integrating with SI-based workflows, double-check converted values to avoid rounding or scale errors.
Limitations
-
This conversion presumes that temperature and pressure remain unchanged, as viscosity varies with these parameters.
-
Accuracy depends on the quality of underlying measurements for dynamic viscosity and fluid density.
-
Centistokes is a non-SI unit, so care is needed when mixing with pure SI unit calculations to prevent inconsistencies.
Frequently Asked Questions
-
What does centistokes [cSt] measure?
-
Centistokes is a unit of kinematic viscosity representing 0.01 stokes or 1 × 10⁻⁶ m²/s, indicating a fluid's resistance to flow considering its density and dynamic viscosity.
-
Why convert centistokes to square meter/second?
-
Converting to square meter per second, the SI unit, standardizes viscosity values for engineering calculations and fluid dynamic modeling.
-
Can this conversion be affected by temperature?
-
Yes, kinematic viscosity varies with temperature and pressure, so consistency in these conditions is important for accurate conversions.
Key Terminology
-
Centistokes (cSt)
-
A non-SI unit of kinematic viscosity equal to 0.01 stokes or 1 × 10⁻⁶ m²/s, representing fluid resistance to flow under gravity.
-
Square meter per second (m²/s)
-
The SI unit of kinematic viscosity, defined as dynamic viscosity divided by fluid density, indicating momentum diffusivity of a fluid.
-
Kinematic Viscosity
-
A fluid property describing its resistance to flow and how velocity gradients diffuse through it, calculated as dynamic viscosity divided by density.
