What does gigapoise measure?

Gigapoise measures dynamic (shear) viscosity in the CGS system, quantifying fluid resistance to shear.

When should I use pound-force second per square foot for viscosity?

It’s used mainly in Imperial/US customary engineering contexts like petroleum and lubrication for viscous fluids.

Why might converted values be so large?

Because 1 GP equals over 2 million lbf·s/ft², values scale up significantly after conversion.

Key Features

Converts dynamic viscosity from gigapoise (GP) to pound-force second/sq. foot (lbf·s/ft²).
Supports handling of very large viscosity values common in rheology and geophysics.
Browser-based and easy to use with clear input and output units.

Examples

2 GP equals 4,177,086.85 lbf·s/ft² calculated by multiplying 2 with the conversion factor.
0.5 GP converts to 1,044,271.71 lbf·s/ft² using the converter's formula.

Common Use Cases

Converting extremely high viscosity data from CGS poise to Imperial units for engineering tasks.
Assessing the viscosity of heavy oils, greases, and tars in petroleum engineering with US customary units.
Calculations in pipe flow and pump design relying on legacy Imperial system viscosity data.

Tips & Best Practices

Ensure input values are within the valid range of your application to avoid numerical overflow.
Use this tool when working with specialized rheological data requiring conversion between unit systems.
Double-check large results as the conversion factor causes values to grow considerably.

Limitations

Large conversion factors can lead to very large numerical outputs, which require careful handling.
Gigapoise is not commonly used outside niche geophysics or materials science, limiting familiarity.
Unit system differences may cause rounding or approximation errors in detailed engineering.
