What Is This Tool?
This tool converts kinematic viscosity measurements from square centimeters per second (cm²/s), a CGS unit, to petastokes [PSt], an astronomically large viscosity unit used in geophysical and planetary scale modeling.
How to Use This Tool?
-
Enter the kinematic viscosity value in square centimeter per second (cm²/s).
-
Select petastokes [PSt] as the target unit for conversion.
-
Click the convert button to see the equivalent value in petastokes [PSt].

Common Use Cases
-
Expressing kinematic viscosity for large-scale geophysical or planetary interior flow studies.
-
Performing unit-scaling exercises in fluid mechanics education to illustrate vast magnitude differences.
-
Modeling extremely large-scale fluid flows where standard laboratory units are insufficient.
Tips & Best Practices
-
Use this conversion primarily for theoretical or pedagogical purposes.
-
Prefer SI units like m²/s for practical engineering and laboratory measurements.
-
Apply scientific notation when dealing with converted values due to their very small size.
-
Be aware that petastokes are rarely used in day-to-day viscosity computations.
Limitations
-
Petastokes units represent extremely large orders of magnitude and are not practical for typical engineering tasks.
-
Converted results may be very small, which can cause readability and interpretation challenges.
-
Most fluid viscosity calculations are better performed with SI or smaller CGS units.
-
Not suitable for everyday laboratory or industrial viscosity measurements.
Frequently Asked Questions
-
What does square centimeter per second measure?
-
It measures kinematic viscosity, describing the ratio of dynamic viscosity to fluid density and the fluid's momentum diffusivity.
-
Why use petastokes for viscosity?
-
Petastokes are used mostly for representing extremely large-scale viscosity values in geophysical or planetary science contexts.
-
Can petastokes be used in everyday engineering?
-
No, petastokes represent very large values and are not practical for standard engineering or laboratory applications.
Key Terminology
-
Square centimeter per second (cm²/s)
-
A CGS unit for kinematic viscosity measuring fluid momentum diffusivity, equal to 1×10⁻⁴ m²/s in SI units.
-
Petastokes [PSt]
-
A unit of kinematic viscosity equal to 10^15 stokes, mainly used for extremely large-scale geophysical or planetary fluid flow analyses.
-
Kinematic viscosity
-
A fluid property defined as dynamic viscosity divided by fluid density, indicating momentum diffusion in a flow.
