What Is This Tool?
This tool converts pressure values from poundal per square foot, a unit in the FPS system, to kilogram-force per square millimeter, a non-SI gravitational unit commonly used in engineering contexts for stress and material strength.
How to Use This Tool?
-
Enter the pressure value in poundal per square foot you wish to convert.
-
Select poundal/square foot as the input unit and kilogram-force per square millimeter as the output unit.
-
Execute the conversion to obtain the equivalent value in kilogram-force/sq. millimeter.
-
Use the results for engineering analysis involving stress, tensile strength, or bearing pressures.
Key Features
-
Converts pressure from poundal/square foot (FPS unit) to kilogram-force/sq. millimeter (gravitational metric unit).
-
Supports pressure unit conversion needed in mechanical engineering and materials science.
-
Provides easy calculations using a defined conversion rate and formula.
-
Browser-based and user-friendly for quick legacy to modern unit translations.
Examples
-
Convert 500 poundal/square foot: 500 × 1.517504900827e-7 = 0.00007587525 kilogram-force/sq. millimeter.
-
Convert 1000 poundal/square foot: 1000 × 1.517504900827e-7 = 0.00015175049 kilogram-force/sq. millimeter.
Common Use Cases
-
Translating old FPS system pressure data into metric gravitational units for updated engineering records.
-
Expressing low pressure values in legacy engineering textbooks and mechanics coursework.
-
Converting pressure for materials testing, including tensile strength and yield strength measurements.
-
Specifying contact pressures or bearing stresses in mechanical component design using metric units.
Tips & Best Practices
-
Confirm that units entered correspond exactly to the poundal/square foot and kilogram-force/sq. millimeter definitions.
-
Use this tool to interpret historical or legacy pressure data for comparison with modern materials testing standards.
-
Be cautious of the small conversion factor to avoid errors from rounding or unit system differences.
-
Note that kilogram-force/sq. millimeter is non-SI and may not be accepted in all international standards.
Limitations
-
Poundal/square foot is an outdated unit and less precise compared to SI pressure units.
-
Conversion factors are very small, requiring careful handling to maintain accuracy.
-
Kilogram-force/sq. millimeter is a non-SI unit, so it may not be accepted under certain international regulations.
-
This tool does not cover conversions beyond these specific units.
Frequently Asked Questions
