What is the short ton (US)?

The short ton, also called the US ton, is a unit of mass defined as exactly 2,000 avoirdupois pounds, commonly used in the United States for commercial and industrial measurements.

Why does the assay ton have different values?

The US assay ton is a historical mining mass unit whose exact weight has varied depending on jurisdiction and practice, leading to different definitions over time.

Can this converter be used for legal contracts?

While it helps approximate mass conversions, users should verify assay ton definitions and consult precise sources before using it in contractual or legal contexts.

What Is This Tool?

This converter translates weight and mass values from the short ton (commonly used in the United States) to the US assay ton, a historical mining unit for reporting precious metal content. It helps relate bulk mass data to assay sample masses used in mining and metallurgy.

How to Use This Tool?

Enter the value in short tons (ton (US)) you wish to convert
Select ton (short) [ton (US)] as the input unit and ton (assay) (US) [AT (US)] as the output unit
Click convert to get the equivalent ton (assay) mass based on the defined conversion rate

Key Features

Converts weight values from ton (short) [US ton] to ton (assay) (US) [AT (US)]
Useful for mining, metallurgical assays, and precious metal quantification
Includes clear conversion rate and practical example calculations
Browser-based tool that is easy to use without prior conversion knowledge

Examples

2 ton (short) [ton (US)] equals 62,206.946490634 ton (assay) (US) [AT (US)]
0.5 ton (short) [ton (US)] equals 15,551.7366226585 ton (assay) (US) [AT (US)]

Common Use Cases

Transforming bulk shipment weights into assay sample masses for precious metal quantification
Assisting mining engineers and assay labs in correlating tonnage data with assay results
Converting historical assay data into modern units for resource estimation and comparison
Supporting contractual settlements based on metal content per assay ton

Tips & Best Practices

Always verify the definition of the assay ton used in your context to avoid ambiguity
Use this converter primarily for approximate mass-to-sample mass translations in mining and assay reporting
Double-check results especially when applied for contractual or legal purposes
Understand that assay ton values may differ by jurisdiction and time period

Limitations

The US assay ton's exact mass varies by jurisdiction and historical usage, which can cause inconsistencies
Assay ton is a sample mass unit, not a strict weight measurement, potentially leading to ambiguities
Precision depends on consistent definitions between reporting frameworks and contracts
