What Is This Tool?
This tool converts dynamic viscosity measurements from poundal second per square foot, an imperial unit, to petapoise [PP], a CGS-derived unit suitable for expressing extremely large viscosity values.
How to Use This Tool?
-
Enter the dynamic viscosity value in poundal second per square foot.
-
Select the source unit as poundal second/square foot.
-
Choose petapoise [PP] as the target unit.
-
Initiate the conversion to get the corresponding viscosity in petapoise.

Examples
-
10 poundal second/square foot equals 1.4881639435685e-13 petapoise [PP].
-
0.5 poundal second/square foot equals 7.4408197178425e-15 petapoise [PP].
Common Use Cases
-
Interpreting or converting historical viscosity data recorded in imperial FPS units to modern SI or CGS scales.
-
Calculating viscosities of lubricants and oils in engineering projects using older unit systems.
-
Describing extremely high viscosities in geophysics and planetary science studies.
-
Performing unit scaling in rheology and computational materials science for ultra-slow flow modeling.
Tips & Best Practices
-
Verify that the input values are in poundal second per square foot before conversion.
-
Use this conversion primarily for contexts involving very large viscosity magnitudes.
-
Be cautious of numerical precision loss due to extremely small conversion multipliers.
-
Cross-check converted values when applying them to high-precision calculations.
Limitations
-
The poundal second per square foot unit is rarely employed in modern measurements.
-
Conversion results yield extremely small decimal numbers that may affect numerical accuracy.
-
Petapoise is suited for very large viscosities and may not be applicable for common fluid viscosity ranges.
Frequently Asked Questions
-
What does poundal second per square foot measure?
-
It is an imperial unit measuring dynamic (absolute) viscosity, representing force over time per area to express fluid resistance to shear flow.
-
What is petapoise used for?
-
Petapoise is a CGS-derived unit for expressing extremely large dynamic viscosity values, often utilized in geophysics and theoretical rheology.
-
Why convert from poundal second/square foot to petapoise?
-
Converting enables translating older imperial FPS viscosity measurements into ultra-large CGS values for comparison with modern scientific data.
Key Terminology
-
Poundal second per square foot
-
An imperial FPS unit of dynamic viscosity defined as force times time divided by area, quantifying fluid resistance to shear.
-
Petapoise [PP]
-
A CGS-derived dynamic viscosity unit equal to 10^15 poise, used for expressing extremely large viscosity values.
