What Is This Tool?
This converter transforms dynamic viscosity values from poundal second per square foot, an imperial unit in the FPS system, to pound per foot per hour, a customary imperial engineering unit. It supports engineers and professionals working with legacy or regional viscosity measurements.
How to Use This Tool?
-
Enter the dynamic viscosity value in poundal second per square foot.
-
Select poundal second/square foot as the input unit.
-
Choose pound per foot per hour (lb/(ft*h)) as the output unit.
-
Click convert to get the equivalent viscosity in pound/foot/hour.
Key Features
-
Converts dynamic viscosity units between poundal second/square foot and pound/foot/hour.
-
Supports engineering and fluid dynamics applications using imperial units.
-
Facilitates interpretation of historical and legacy viscosity data.
-
Browser-based and easy to use for quick conversions.
-
Accurately applies the fixed conversion rate of 1 poundal second/square foot = 3599.9999999974 pound/foot/hour.
Examples
-
1 poundal second/square foot is equal to 3600 pound/foot/hour (rounded).
-
0.5 poundal second/square foot converts to 1800 pound/foot/hour.
Common Use Cases
-
Specifying viscosities of lubricants and oils in older FPS or imperial unit systems.
-
Performing fluid dynamics or pump and bearing analyses with imperial measurements.
-
Converting historical experimental viscosity data to current or regional standards.
-
Reporting viscosity values in US-customary engineering documentation.
-
Conducting industrial process calculations involving fluid flow in imperial units.
Tips & Best Practices
-
Verify the proper input unit before converting to ensure accuracy.
-
Be mindful of the difference in time units between seconds and hours to avoid scaling mistakes.
-
Use this tool to bridge between legacy FPS-based viscosity data and modern engineering requirements.
-
Check regional or project-specific unit standards to maintain consistency.
-
Cross-verify conversion results when dealing with critical or historical data.
Limitations
-
Conversion involves a change in time base from seconds to hours, requiring careful attention to scaling.
-
Minor rounding may occur due to floating-point precision in calculations.
-
The poundal unit is less commonly used in modern practice, so conversions are often necessary to interface with standard or SI units.
Frequently Asked Questions
-
What does the unit poundal second per square foot measure?
-
It measures dynamic viscosity in the imperial FPS system, representing a force of one poundal applied over one second distributed across one square foot.
-
Why convert from poundal second/square foot to pound/foot/hour?
-
This conversion allows users to switch between FPS-based viscosity units and customary imperial units that use hour-based time, facilitating engineering calculations and legacy data comparison.
-
Are there any accuracy issues with this conversion?
-
Slight rounding may occur due to floating-point precision, and users should be cautious about the time base difference in scaling.
Key Terminology
-
Poundal second per square foot
-
An FPS imperial unit of dynamic viscosity quantifying fluid resistance to shear, defined as force applied over time per unit area.
-
Pound per foot per hour [lb/(ft*h)]
-
An imperial engineering unit of dynamic viscosity expressing internal fluid resistance to shear using customary units with an hour-based time component.
