What Is This Tool?

This online converter helps translate measurements from the ton (long) used in UK and maritime contexts to the US assay ton, which is common in mining and precious-metal content reporting.

How to Use This Tool?

  • Enter the value in the ton (long) [ton (UK)] unit you want to convert.
  • Select the target unit as ton (assay) (US) [AT (US)].
  • Click the convert button to see the equivalent value in the assay ton unit.
  • Use the results to aid in historical data interpretation or mining assay calculations.

Key Features

  • Converts long ton (UK) mass units to US assay ton units accurately.
  • Ideal for integrating historical UK shipping and trade data with US assay standards.
  • Supports specialized mass unit conversions used in mining and precious metal assaying.
  • Browser-based and easy to use with clear input and output fields.
  • Includes detailed examples demonstrating common conversions.

Examples

  • 2 ton (long) [ton (UK)] converts to 69,671.78006951 ton (assay) (US) [AT (US)].
  • 0.5 ton (long) [ton (UK)] converts to 17,417.9450173775 ton (assay) (US) [AT (US)].

Common Use Cases

  • Converting historical UK shipping and ship displacement figures to assay ton units.
  • Pricing or measuring bulk commodities in legacy British trade data with US assay standards.
  • Assisting in the reporting of precious-metal concentrations on assay certificates.
  • Estimating resources by converting old assay data to modern units like grams per tonne.
  • Reconciling historical mining and legal documents using standardized mass units.

Tips & Best Practices

  • Always specify explicit mass units when dealing with assay tons to avoid confusion.
  • Double-check unit definitions if converting between different assay ton standards.
  • Handle large numerical results carefully to maintain calculation accuracy.
  • Use consistent units across datasets when integrating historical and modern data.
  • Refer to official assay and trade standards when reporting converted values.

Limitations

  • The assay ton varies historically by jurisdiction, which can cause ambiguity without explicit mass definitions.
  • Conversion assumes specific masses; different assay ton standards may lead to discrepancies.
  • Large conversion factors can result in complex numbers requiring careful numerical handling.

Frequently Asked Questions

What is the ton (long) [ton (UK)] used for?
It is an imperial mass unit historically used in the UK, especially for ship displacement and bulk commodity measurements.

Why does the US assay ton (AT) have variable mass?
Because its exact mass has historically depended on jurisdiction and practice, modern usage requires specifying exact mass units.

How can this conversion help in mining?
It translates bulk mass units into assay tons needed for reporting precious metal content and contract settlements.

Key Terminology

Ton (long) [ton (UK)]
An imperial mass unit equal to 2,240 avoirdupois pounds, historically used in the UK and maritime contexts.
Ton (assay) (US) [AT (US)]
A historical mining mass unit used to define sample masses for precious-metal content reporting, with mass varying by jurisdiction.
Assay
A process of testing ore or metal content to determine precious metal concentrations.
