The poundal is a unit of force in the foot–pound–second system used to express force or weight in FPS mechanics.

What does ton (assay) (US) represent?

It is a historical mining mass unit used for standard sample mass in precious-metal assay, with varying mass definitions depending on jurisdiction.

Can I use this conversion for precise engineering calculations?

No, because the poundal is a force unit and the ton (assay) is a historically variable mass unit, exact conversions require contextual assumptions.

What Is This Tool?

This converter allows you to transform values measured in poundals, a unit of force from the foot–pound–second system, into US assay tons, a historical mass unit used primarily in mining and precious-metal assays.

How to Use This Tool?

Enter the numeric value in poundal [pdl] you wish to convert.
Select the source unit as poundal [pdl].
Choose the target unit ton (assay) (US) [AT (US)].
Click convert to see the equivalent amount in assay tons.
Use the result for interpreting mining assay reports or engineering data involving FPS units.

Key Features

Converts poundal (pdl) force units to ton (assay) (US) [AT (US)] mass units
Useful for reconciling classical FPS engineering data with mining assay measurements
Handles units relevant in both physics and historical metallurgical contexts
Browser-based and easy to use without specialized software
Supports interpretation of historical and contractual ore settlement data

Examples

2 poundals [pdl] convert to approximately 0.965946374 ton (assay) (US) [AT (US)]
5 poundals [pdl] equal about 2.414865935 ton (assay) (US) [AT (US)]

Common Use Cases

Interpreting classical dynamics problems and older engineering ballistics texts using FPS units
Reporting precious-metal concentrations on assay certificates using assay tons
Calculating ore shipment settlements based on metal content per assay ton
Converting legacy FPS force measurements into historically defined mass units for resource estimation

Tips & Best Practices

Be aware that poundal is a unit of force whereas ton (assay) (US) is a mass unit, so conversions require contextual understanding
Specify the exact assay ton definition used due to jurisdictional variability
Use conversion results as guidance when interpreting historical data rather than precise engineering calculations
Cross-reference with modern units such as grams per tonne for resource reporting

Limitations

Poundal is fundamentally a force unit, while ton (assay) is a mass unit with historically varying definitions
Direct conversion assumes contextual equivalences not always physically exact
The US assay ton’s mass varies by jurisdiction, so precise use requires clarifying the applied standard

Frequently Asked Questions
