What Is This Tool?
This converter facilitates the transformation of dynamic viscosity measurements from pound/foot/second to poundal second/square foot. Both units are part of the imperial system and describe a fluid's resistance to shear flow. The tool simplifies engineering and industrial calculations by providing a straightforward way to switch between these two units.
How to Use This Tool?
-
Enter the value in pound/foot/second in the input field
-
Select poundal second/square foot as the target unit
-
Click the convert button to see the equivalent value
-
Review the result displayed with the same numerical value due to the direct conversion rate
Key Features
-
Converts viscosity dynamic units within the imperial and FPS measurement systems
-
Supports fluid flow and shear stress analysis for engineering applications
-

-
0.1 pound/foot/second equals 0.1 poundal second/square foot
Common Use Cases
-
Engineering calculations involving fluid flow and shear stress using imperial units
-
Specifying viscosities of lubricants, hydraulic fluids, and process fluids in US-based equipment
-
Interpreting or converting historical viscosity data recorded in FPS units
-
Conducting pump and bearing analyses with retained imperial unit measurements
-
Laboratory measurements and quality control with instrumentation calibrated in imperial units
Tips & Best Practices
-
Ensure unit consistency when combining data from different measurement systems
-
Be aware of the difference between pound-force and poundal as force units despite identical numerical conversions
-
Use this converter to maintain continuity in legacy imperial or FPS-based engineering datasets
-
Cross-check numerical values when integrating SI unit data within imperial frameworks
-
Utilize the tool for quick conversions during lubricant and fluid specification reviews
Limitations
-
The conversion rate is numerically one, but force unit differences require careful interpretation
-
Units involved are less commonly used outside imperial and FPS contexts compared to SI units
-
Not intended for direct scientific calculations requiring SI unit precision
-
Requires user attention to avoid confusion between pound-force and poundal units
-
May not suit international applications relying primarily on pascal-seconds
Frequently Asked Questions
-
What is the conversion rate between pound/foot/second and poundal second/square foot?
-
The conversion rate is 1:1, meaning one pound/foot/second is equal to one poundal second per square foot.
-
Why convert between these specific units of dynamic viscosity?
-
Converting between these units helps maintain consistency in engineering and industrial settings, especially when using legacy or FPS-based data.
-
Are pound/foot/second and poundal second/square foot widely used internationally?
-
No, these units are primarily used in imperial and FPS contexts, whereas most international scientific work uses SI units like pascal-seconds.
Key Terminology
-
Pound/foot/second
-
An imperial unit of dynamic viscosity indicating one pound-force second per square foot, describing fluid resistance to shear.
-
Poundal second/square foot
-
An imperial FPS unit measuring dynamic viscosity by applying one poundal force over one second per square foot.
-
Dynamic viscosity
-
A measure of a fluid's internal resistance to flow and shear stress.
