What Is This Tool?
This converter allows users to transform values measured in the US assay ton, a historical unit used in mining and precious-metal assays, into gamma, a very small mass unit suitable for trace-level analysis.
How to Use This Tool?
-
Enter the mass value measured in ton (assay) (US) [AT (US)].
-
Select the target unit as gamma.
-
Click convert to obtain the equivalent mass in gamma units.
Key Features
-
Converts historical mass units commonly used in precious-metal assay documentation to microgram units.
-
Supports detailed trace mass quantification necessary in analytical chemistry and geochemistry.
-
Browser-based tool that simplifies complex unit conversions for mining, assay labs, and environmental monitoring.
Examples
-
2 Ton (assay) (US) [AT (US)] is equal to 58333340 Gamma.
-
0.5 Ton (assay) (US) [AT (US)] converts to 14583335 Gamma.
Common Use Cases
-
Reporting gold or silver concentration on assay certificates as ounces per assay ton.
-
Calculating payments or settlements in mining contracts based on precious metal content per assay ton.
-
Translating historical assay data into modern mass units for resource assessment and comparison.
-
Measuring trace sample masses in geochemistry and environmental monitoring.
Tips & Best Practices
-
Ensure the assay ton unit is explicitly defined to avoid discrepancies due to historical variations.
-
Handle large numerical gamma results carefully to prevent input or interpretation errors.
-
Use this conversion to facilitate precise reporting of micro-scale precious metal masses in scientific contexts.
Limitations
-
The ton (assay) (US) [AT (US)] unit has historically varied, so results may differ without clear unit definitions.
-
Conversions to gamma produce very large numerical values when starting from large assay ton values, requiring careful numerical handling.
Frequently Asked Questions
-
What is a ton (assay) (US) [AT (US)]?
-
It is a historical mining mass unit used to report precious metal content, whose exact mass can vary based on region and practice.
-
Why use gamma as a unit?
-
Gamma is a very small mass unit equal to one microgram, useful for expressing trace-level sample masses in analytical and environmental sciences.
-
Can the assay ton vary between reports?
-
Yes, its mass has varied historically and regionally, so reports often specify exact masses to avoid ambiguity.
Key Terminology
-
Ton (assay) (US) [AT (US)]
-
A historical mining mass unit used to define standard sample masses for precious-metal content reporting, varying by jurisdiction and practice.
-
Gamma
-
A non-SI unit equal to one microgram, used to measure very small masses in analytical chemistry and environmental science.
