Common Use Cases
-
Specifying lubricant or oil viscosities in legacy or US-customary engineering data
-
Performing viscous flow calculations in piping, bearings, or rotating equipment using imperial units
-
Converting viscosity data reported with hour-based time units for fluid dynamics analyses
-
Interpreting historical experimental viscosity data in FPS-based units for comparison
Tips & Best Practices
-
Verify unit consistency in your engineering workflow before converting
-
Be careful to account for the difference in time units when interpreting results
-
Use this converter mainly when working within imperial unit frameworks
-
Consult technical documentation to ensure proper application of viscosity values
Limitations
-
Assumes consistent imperial definitions for force and area units, which can affect precision
-
Time unit difference (hours to seconds) requires careful handling to avoid errors
-
Primarily suitable for engineering contexts using imperial measurements, not SI-centric workflows
Frequently Asked Questions
-
What does pound/foot/hour measure in viscosity?
-
It expresses a fluid's internal resistance to shear using force-time per unit area in the imperial system.
-
Why convert from pound/foot/hour to poundal second/square foot?
-
To translate viscosity values from an hourly imperial time base to a second-based FPS unit for engineering analyses.
-
Can this conversion be used in SI unit workflows?
-
No, this tool is intended for contexts retaining imperial units and may require additional steps for SI conversions.
Key Terminology
-
Pound/foot/hour [lb/(ft*h)]
-
An imperial dynamic viscosity unit expressing internal fluid resistance using force-time per unit area with hour-based time.
-
Poundal second/square foot
-
An imperial FPS unit measuring dynamic viscosity as force applied per second over an area of one square foot.
-
Dynamic viscosity
-
A measure of a fluid's internal resistance to shear flow, relating shear stress to velocity gradient.
