What Is This Tool?
This converter facilitates the translation of force values from gram-force (gf), a small force unit based on standard gravity, to poundal (pdl), a unit used in the foot–pound–second system. It supports users in handling legacy engineering data, classical mechanics problems, and precision force measurements.
How to Use This Tool?
-
Enter the force value in gram-force [gf]
-
Select gram-force as the source unit and poundal as the target unit
-
Click the convert button to see the equivalent force in poundal [pdl]
Key Features
-
Converts force values from gram-force [gf] to poundal [pdl]
-
Supports small-force measurement conversions
-
Browser-based and simple to use
-
Useful for legacy and educational applications
-
Provides quick and reliable conversions based on established rates
Examples
-
Convert 10 gf to poundal: 10 × 0.0709316353 = 0.709316353 pdl
-
Convert 50 gf to poundal: 50 × 0.0709316353 = 3.546581765 pdl
Common Use Cases
-
Determining actuation forces for tactile switches and keyboard keys
-
Rating small springs, clips, and load cells in engineering tests
-
Converting classical mechanics problems using FPS units
-
Interpreting legacy ballistics or archival technical data
-
Calibrating small forces in precision balances and lab equipment
Tips & Best Practices
-
Ensure that force values represent small-scale forces suitable for these units
-
Use the converter primarily for legacy data or educational problems
-
Be aware of the non-SI nature of gram-force and legacy status of poundal
-
Double-check conversions when precise engineering calculations are required
Limitations
-
Gram-force depends on standard gravity, which can slightly vary by location
-
Poundal is a deprecated unit mainly useful for legacy or academic use
-
Both units only apply well to relatively small force measurements
-
Not appropriate for high-force scale or modern engineering standards
Frequently Asked Questions
-
What is a gram-force?
-
A gram-force is a non-SI unit of force equal to the force exerted by one gram under standard gravity, approximately 0.00980665 newtons.
-
What is a poundal used for?
-
A poundal is a unit of force in the foot–pound–second system, used for classical mechanics problems, legacy engineering data, and small-force calculations involving FPS units.
-
Why convert between gram-force and poundal?
-
Conversion helps translate small practical force measurements into the FPS system, facilitating interoperability between SI-based and legacy FPS systems.
Key Terminology
-
Gram-force [gf]
-
A non-SI unit of force equal to the force exerted by a one-gram mass under standard gravity.
-
Poundal [pdl]
-
A unit of force in the FPS system that produces an acceleration of 1 foot per second squared on one avoirdupois pound.
-
Standard Gravity
-
The conventional acceleration due to gravity, defined as 9.80665 meters per second squared, used to relate mass to force.
