What Is This Tool?
This tool converts amounts from the ton (assay) (US) [AT (US)], a historical mining mass unit, into poundals [pdl], a force unit in the foot–pound–second system. It helps integrate mining assay data with classical mechanics and engineering calculations.
How to Use This Tool?
-
Enter the value in ton (assay) (US) [AT (US)] that you want to convert
-
Select the target unit as poundal [pdl]
-
Click convert to see the equivalent value in poundals
Key Features
-
Converts from US assay ton to poundal force units accurately per defined conversion rates
-
Supports integration of historical mining mass data with FPS force measurements
-
Browser-based and easy to use for niche scientific and engineering conversions
Examples
-
1 ton (assay) (US) [AT (US)] equals 2.0705083157 poundal [pdl]
-
5 ton (assay) (US) [AT (US)] equals 10.3525415785 poundal [pdl]
Common Use Cases
-
Reporting precious-metal content as ounces per assay ton in mining assay certificates
-
Calculating contractual payments for metal content per assay ton in ore shipments
-
Converting historical assay data for resource estimation into force units used in engineering
-
Solving classical dynamics problems and ballistics engineering using FPS units
Tips & Best Practices
-
Confirm the exact mass definition of the US assay ton used in your data before converting
-
Remember poundal is a force unit, so consider acceleration context when interpreting results
-
Use this conversion primarily for historical or specialized mining and engineering data integration
Limitations
-
The US assay ton varies by jurisdiction, so conversions may not be universally consistent
-
Poundal measures force, not mass, so direct substitution with mass units can cause errors
-
This conversion is specialized and uncommon in modern scientific practice
Frequently Asked Questions
-
What is a ton (assay) (US) [AT (US)]?
-
It is a historical mining mass unit used to report the sample mass for precious metal content, whose exact value varies by jurisdiction and practice.
-
What does a poundal measure?
-
A poundal is a force unit in the foot–pound–second system, representing the force needed to accelerate one pound mass at one foot per second squared.
-
Can I use this converter for modern mass or force conversions?
-
This tool is mainly for specialized historical or niche applications and may not suit standard modern scientific unit conversions.
Key Terminology
-
Ton (assay) (US) [AT (US)]
-
A historical mining mass unit used for sample mass reporting in precious-metal assays, with variable exact mass depending on jurisdiction.
-
Poundal [pdl]
-
A unit of force in the foot–pound–second system, defined as the force required to accelerate a one-pound mass at one foot per second squared.
-
FPS System
-
A system of units using foot, pound, and second as base units, commonly used in classical mechanics.
