What is the US assay ton (AT)?

It is a historical mass unit used in mining assay reporting for precious metals, with variable exact mass by jurisdiction.

Why convert to pound (troy or apothecary)?

This unit was traditionally used in apothecaries and bullion measures, making the conversion useful for interpreting historical precious-metal weights.

Is the troy pound still commonly used today?

No, the troy pound is mostly obsolete, with the troy ounce remaining as the standard for bullion measurements.

What Is This Tool?

This converter transforms weight measurements from the US assay ton, a historical mining mass unit used in precious-metal assay reporting, into the troy or apothecary pound, an older unit historically applied in apothecaries and bullion measurement.

How to Use This Tool?

Enter the weight value in ton (assay) (US) [AT (US)].
Select the target unit as pound (troy or apothecary).
Click convert to see the equivalent mass in troy pounds based on the specific conversion ratio.

Key Features

Converts assay ton (US) to troy/apothecary pounds for precious-metal content analysis.
Facilitates translation of historical assay and bullion data to traditional troy units.
Supports mining industry, numismatics, and archival research needs.

Examples

5 Ton (assay) (US) [AT (US)] converts to 0.390720923 Pound (troy or apothecary).
10 Ton (assay) (US) [AT (US)] converts to 0.781441846 Pound (troy or apothecary).

Common Use Cases

Reporting gold or silver concentration on assay certificates as ounces per assay ton.
Contractual calculations for ore shipments based on precious-metal content per assay ton.
Interpreting historical apothecary prescriptions and bullion records featuring troy weight.
Converting older assay data into units consistent with precious-metal weight systems.

Tips & Best Practices

Specify the exact mass of the assay ton used to ensure precise conversion.
Contextualize results with relevant historical or jurisdictional standards.
Be aware that troy pounds are mainly obsolete; troy ounces remain in common bullion use.

Limitations

Mass of the ton (assay) (US) [AT (US)] varies by region and practice, potentially affecting accuracy.
Troy pound is largely outdated, limiting its modern-day practical application.
