Numerical precision must be considered when working across such different magnitude units
-
This tool focuses solely on dynamic viscosity unit conversion between specified units
-
Users should verify the context suitability when using converted results in scientific calculations
Frequently Asked Questions
-
What does pound/foot/hour measure in viscosity terms?
-
It represents an imperial unit of dynamic viscosity indicating a fluid’s internal resistance to shear, relating shear stress to velocity gradient.
-
What is petapoise used for?
-
Petapoise is a CGS-derived unit measuring extremely large dynamic viscosities, useful in geophysics, rheology, and modeling ultra-slow flows.
-
Why convert from pound/foot/hour to petapoise?
-
To translate viscosity values from imperial engineering units into large-scale CGS units suited for scientific research and material studies.
-
Is the conversion precise for all viscosity ranges?
-
While mathematically precise, the small conversion factor means pound/foot/hour is unsuitable for ultra-high viscosities expressed in petapoise.
Key Terminology
-
Pound/foot/hour [lb/(ft*h)]
-
An imperial dynamic viscosity unit expressing fluid resistance to shear in customary force-time per area units.
-
Petapoise [PP]
-
A CGS-based dynamic viscosity unit equal to 10^15 poise, used for denoting very large viscosity magnitudes.
-
Dynamic viscosity
-
A measure of a fluid’s internal resistance to flow or shear stress, relating velocity gradient to shear force.
