Examples
-
Convert 5 poundal second/square foot to kilogram-force second/square meter: 5 × 0.1517504901 = 0.7587524505 kilogram-force second/square meter.
-
Convert 10 poundal second/square foot to kilogram-force second/square meter: 10 × 0.1517504901 = 1.517504901 kilogram-force second/square meter.
Common Use Cases
-
Evaluating viscosities of lubricants and oils using imperial FPS units in engineering contexts.
-
Performing fluid dynamics or pump and bearing analyses when working with older unit systems.
-
Converting historical or legacy experimental viscosity data from FPS units to non-SI units for comparison.
-
Reporting or interpreting viscosity in documents or equipment specifications based on kilogram-force units.
-
Preparing fluid property data for computational fluid dynamics or rheology analyses by converting to standard units.
Tips & Best Practices
-
Verify the units of your source data before conversion to ensure accuracy.
-
Use the conversion factor provided to maintain consistency across calculations.
-
Remember that both units are non-SI and may need further conversion to pascal-second for modern standards.
-
Cross-check converted values when working with legacy data due to potential minor unit inconsistencies.
-
Apply this conversion when integrating older engineering data into modern modeling or simulation tools.
Limitations
-
Both poundal second/square foot and kilogram-force second/square meter are non-SI units, requiring additional conversion to SI units such as pascal-second for some applications.
-
Accuracy depends on correctly applying the fixed conversion factor without rounding during intermediate steps.
-
Legacy data may contain minor inconsistencies in unit usage which can affect conversion results.
Frequently Asked Questions
-
What does poundal second per square foot measure?
-
It is an imperial FPS unit of dynamic viscosity representing the force of one poundal applied over one second across an area of one square foot.
-
Why convert between poundal second/square foot and kilogram-force second/square meter?
-
Users convert these units to translate fluid viscosity data between imperial FPS units and older non-SI units for standardized reporting and engineering calculations.
-
Is kilogram-force second/square meter an SI unit?
-
No, it is a non-SI unit commonly used in older engineering contexts but equals 9.80665 pascal-second in SI units.
Key Terminology
