Frequently Asked Questions
-
What does nanopoise measure?
-
Nanopoise measures dynamic (shear) viscosity as a submultiple of the poise, commonly used for very small fluid viscosities in CGS units.
-
Why convert nanopoise to pound-force second per square foot?
-
Converting allows translating viscosity data from micro- and nanofluidic contexts into Imperial units used in petroleum engineering and lubrication applications.
-
Is this conversion suitable for all viscosity ranges?
-
This conversion is best for very small to heavy fluid viscosities, but numerical precision should be considered due to the large scale difference.
Key Terminology
