-
Ideal for applications in automotive oils, hydraulic fluids, and fluid dynamics research.
-
Browser-based and easy to use without requiring any installation.
Examples
-
2 St equals 200 square millimeter per second (mm²/s).
-
0.5 St corresponds to 50 mm²/s.
Common Use Cases
-
Specifying kinematic viscosity in lubricants and engine oils, especially when reported in centistokes.
-
Analyzing sedimentation, particle settling, and aerosol behavior in geophysical and hydraulic studies.
-
Laboratory measurements in fluid dynamics and rheology involving Reynolds number and flow analysis.
Tips & Best Practices
-
Use this converter to switch between CGS and SI viscosity units for consistent data comparisons.
-
Apply conversions primarily in controlled environments as viscosity values can vary with temperature and fluid makeup.
-
Check measurement instruments’ resolution when dealing with very small viscosity values to ensure accuracy.
Limitations
-
Viscosity can be influenced by temperature and fluid composition, which this converter does not adjust for.
-
Measurement precision may be limited by the accuracy of instrumentation when converting small values.
-
Assumes ideal conditions for unit conversion without accounting for external physical variables.
Frequently Asked Questions
-
What does 1 stokes equal in square millimeters per second?
-
1 stokes equals 100 square millimeter per second according to the standard conversion factor.
-
Why convert stokes to square millimeter per second?
-
Converting stokes to square millimeter per second offers a unit more commonly used in industrial and lab settings for precision and standardization.
-
Can temperature affect the viscosity values converted by this tool?
-
Yes, viscosity can change with temperature, and this converter assumes ideal conditions without compensating for temperature variations.
