What Is This Tool?
This tool performs viscosity conversions from gigapoise, a CGS system unit for very high dynamic viscosity, to poundal second per square foot, an imperial unit used primarily in older engineering contexts. The conversion helps users compare and analyze fluid behavior across different measurement systems.
How to Use This Tool?
-
Enter the viscosity value in gigapoise [GP] you want to convert
-
Select the target unit as poundal second per square foot
-
Click the convert button to get the equivalent viscosity in imperial units

0.5 GP converts to 33598448.757 poundal second/square foot
Common Use Cases
-
Rheology studies of highly viscous substances like cured polymers and bitumen
-
Geophysical modeling of slow rock or ice creep over geological periods
-
Engineering calculations involving lubricants and oils in imperial units
-
Analyzing fluid-dynamics problems using FPS system conventions
-
Converting older experimental viscosity measurements for modern comparison
Tips & Best Practices
-
Ensure consistent shear flow conditions when applying conversions
-
Clearly specify units to avoid confusion with less common imperial terms
-
Double-check results due to the large magnitude difference between units
-
Use conversions mainly for Newtonian fluids or appropriate contexts
-
Consider unit system differences in engineering or scientific reports
Limitations
-
Significant magnitude and unit system differences require careful precision
-
Imperial viscosity units are less common in modern scientific practice
-
Conversions may not directly apply to non-Newtonian fluids without adjustment
Frequently Asked Questions
-
What does gigapoise measure?
-
Gigapoise quantifies dynamic or shear viscosity, measuring the resistance a fluid shows to shear flow, especially at very high values.
-
Why convert gigapoise to poundal second/square foot?
-
Converting between these units helps compare viscosity data measured in CGS with those reported in imperial units, useful for engineering and historical data interpretation.
-
Are conversions applicable for all fluid types?
-
Conversions assume consistent shear flow and are most accurate for Newtonian fluids; they may require additional considerations for non-Newtonian fluids.
Key Terminology
-
Gigapoise [GP]
-
A CGS unit for dynamic viscosity equal to 10^9 poise or 10^8 pascal-seconds, used for very viscous fluids.
-
Poundal second/square foot
-
An imperial unit of dynamic viscosity representing the force of a poundal applied over one second across one square foot.
-
Dynamic Viscosity
-
A measure of a fluid’s resistance to shear flow, quantified as shear stress per unit shear rate.
