What Is This Tool?
This converter transforms kinematic viscosity measurements from stokes (St), a CGS unit defined as one square centimetre per second, into square meter per hour (m²/h), a unit used for larger scale and slower time frames. The tool helps compare viscosity values measured in seconds with those expressed in hours, useful in various engineering and scientific fields.

Tips & Best Practices
-
Ensure correct time scaling when applying hourly units for viscosity models.
-
Use conversions for steady conditions, noting temperature and pressure can affect viscosity.
-
For high precision work, verify calculations with SI base units to avoid rounding errors.
-
Apply conversions carefully when comparing small-scale lab data with large-scale field conditions.
Limitations
-
Conversion assumes steady-state conditions and direct proportionality between units.
-
May not account for changes in temperature or pressure influencing viscosity.
-
Rounding errors can occur in precise scientific measurements.
-
Hourly unit conversions require careful time scale adjustments in modeling.
Frequently Asked Questions
-
What does one stokes represent in kinematic viscosity?
-
One stokes (St) is a CGS unit of kinematic viscosity, defined as one square centimetre per second (1 St = 1 cm²/s), representing a fluid's resistance to flow.
-
Why convert stokes to square meters per hour?
-
This conversion is helpful for expressing viscosity in terms suitable for slow, large-scale flows where time is measured in hours, such as groundwater or glacier flow.
-
What is the conversion factor between stokes and square meters per hour?
-
The conversion rate is 1 stokes [St] equals 0.36 square meter/hour [m²/h].
Key Terminology
-
Stokes (St)
-
A CGS unit of kinematic viscosity equal to one square centimetre per second, used to express fluid resistance to flow.
-
Square meter per hour (m²/h)
-
A unit of kinematic viscosity representing the area transported per hour, useful for slow fluid flow applications.
-
Kinematic Viscosity
-
A measure of a fluid’s resistance to flow under gravity, expressed as the ratio of dynamic viscosity to density.
