What Is This Tool?
This converter transforms values of kinematic viscosity from stokes, a common CGS unit, into petastokes, which represent extremely large-scale viscosity measurements used mainly in geophysics and planetary science.
How to Use This Tool?
-
Enter the viscosity value in stokes (St) that you want to convert
-
Choose petastokes (PSt) as the target unit
-
Review the converted value displayed instantly in petastokes
-
Use the output for comparisons or educational purposes in large-scale fluid dynamics scenarios
Key Features
-
Converts kinematic viscosity units from stokes (St) to petastokes (PSt)
-
Supports large-scale viscosity measurements suitable for theoretical and planetary studies
-
Useful for comparing laboratory results with geophysical or planetary fluid dynamics data
-

Examples
-
Convert 5 St to petastokes resulting in 5 × 1e-15 PSt or 5e-15 PSt
-
Convert 1,000 St equal to 1,000 × 1e-15 PSt or 1e-12 PSt
Common Use Cases
-
Specifying kinematic viscosity in lubricants and engine oils in laboratory settings with stokes
-
Estimating viscosity values for extremely large-scale geophysical flows such as mantle convection
-
Pedagogical exercises illustrating differences between typical lab units and astronomically large values
-
Analyzing particle settling, sedimentation, and flow in environmental and geophysical fluid dynamics
Tips & Best Practices
-
Verify that your original viscosity measurement is in stokes before converting
-
Use petastokes mainly for theoretical or educational contexts due to its large magnitude
-
Consider using SI units (m²/s) for practical engineering or everyday calculations
-
Double-check conversion results against known scales for accuracy in your application
Limitations
-
Petastokes units are rarely applied in practical engineering due to their extremely large size
-
Values at this scale are typically preferred to be expressed in SI units (m²/s) for computations
-
The unit is generally reserved for theoretical models, planetary science, and educational use
-
Precision concerns and limited everyday relevance reduce the unit's practical adaptability
Frequently Asked Questions
-
What is a stokes (St)?
-
A stokes is a CGS unit of kinematic viscosity defined as one square centimeter per second, commonly used to measure fluid resistance to flow.
-
When should I use petastokes (PSt)?
-
Petastokes are used for estimating extremely large viscosity values in fields like geophysics or planetary science, mainly in theoretical or pedagogical contexts.
-
Can I use petastokes for everyday engineering?
-
No, petastokes units are not practical for daily engineering work; SI units like square meters per second are preferred instead.
Key Terminology
-
Stokes (St)
-
A CGS unit of kinematic viscosity equal to one square centimeter per second, used to quantify fluid resistance to flow.
-
Petastokes (PSt)
-
A unit of kinematic viscosity equal to 10^15 stokes, used mainly for very large-scale geophysical or planetary flow measurements.
-
Kinematic Viscosity
-
A fluid property defined as the ratio of dynamic viscosity to density, representing momentum diffusion within the fluid.
