What Is This Tool?
This online converter transforms force measurements from poundal (pdl), a unit in the foot–pound–second system, into ton-force (metric) (tf), a non-SI unit expressing force exerted by a metric tonne under gravity. It facilitates handling legacy FPS data and adapting it to metric engineering contexts.
How to Use This Tool?
-
Enter the value measured in poundal [pdl] into the input field.
-
Select poundal as the source unit and ton-force (metric) as the target unit.
-
Click the convert button to calculate the equivalent force in ton-force (metric) [tf].
-
View the result displayed instantly for further use or analysis.
Key Features
-

Assists in converting legacy FPS system data to metric forces.
Examples
-
Convert 1000 poundal to ton-force (metric): 1000 × 0.0000140981 = 0.0140981 tf.
-
Convert 500 poundal to ton-force (metric): 500 × 0.0000140981 = 0.00704905 tf.
Common Use Cases
-
Translating smaller FPS force measurements to metric units for engineering projects.
-
Evaluating lifting capacities of cranes, hoists, and winches with metric ton-force values.
-
Specifying compressive loads in civil and mechanical engineering applications.
-
Converting legacy engineering, ballistics, or archival FPS data into metric forces.
-
Describing anchoring, towing, or mooring forces in marine and heavy equipment operations.
Tips & Best Practices
-
Double-check input values to ensure accuracy in unit conversion.
-
Use this converter primarily for legacy data or academic problems involving FPS units.
-
Apply the results in contexts appropriate for the ton-force (metric) unit, such as heavy lifting or structural load specifications.
-
Handle small numerical values carefully due to the conversion factor’s small scale.
-
Combine this tool with other unit converters when working across different measurement systems.
Limitations
-
Poundal is mostly deprecated and mainly relevant for historical or academic purposes.
-
The conversion factor is very small, so calculations may require careful numerical handling.
-
Not intended for applications requiring modern SI units directly.
-
Precision may be affected in cases involving extremely large or tiny force values.
Frequently Asked Questions
-
What does one poundal represent?
-
One poundal is the force that causes an acceleration of one foot per second squared on an object with a mass of one avoirdupois pound, used in the FPS system.
-
What is a ton-force (metric)?
-
A metric ton-force is the force exerted by a mass of one metric tonne acted upon by standard gravity, equal to 9,806.65 newtons.
-
Why convert poundal to ton-force (metric)?
-
Conversion helps translate smaller FPS-based forces into more practical metric units used in engineering, heavy lifting, and modern industrial contexts.
Key Terminology
-
Poundal [pdl]
-
A unit of force in the FPS system defined as the force needed to accelerate one avoirdupois pound at one foot per second squared.
-
Ton-force (metric) [tf]
-
A non-SI metric force unit equal to the force exerted by one metric tonne mass under standard gravity.
-
Foot–pound–second (FPS) system
-
A measurement system using feet, pounds, and seconds as fundamental units, commonly historical for force and mechanics.
