What Is This Tool?
This online converter allows you to transform weight measurements from grams (g), a common SI unit for small masses, into the US assay ton (AT), a traditional mining mass unit used for precious metal assays.
How to Use This Tool?
-
Enter the mass value in grams into the input field.
-
Select 'gram [g]' as the unit to convert from.
-
Choose 'ton (assay) (US) [AT (US)]' as the unit to convert to.
-
Click the convert button to see the equivalent mass in assay tons.
Key Features
-
Accurate conversion from gram to US assay ton using a defined rate.
-
Specialized for mining and precious metal assay applications.
-
User-friendly interface suitable for scientific and industry professionals.
-
Browser-accessible tool with no installation needed.
Examples
-
10 grams equals 0.342857104 US assay tons.
-
50 grams equals 1.71428552 US assay tons.
Common Use Cases
-
Quantifying precious metal content in ore samples using grams and assay tons.
-
Comparing and reporting metal concentrations on assay certificates.
-
Performing contractual calculations for ore shipments based on assay ton measurements.
-
Converting historical assay records into modern units for resource evaluation.
Tips & Best Practices
-
Always verify the jurisdiction and definition of the assay ton being used due to historical variations.
-
Use this converter primarily for precious metal and mining-related conversions.
-
Consult assay certificates or contractual documents for specifics on mass units employed.
-
Prefer metric units for broader general applications to avoid ambiguity.
Limitations
-
The US assay ton's exact mass has changed across jurisdictions and time, causing possible ambiguity.
-
Assay tons are specialized units mainly for precious metal contexts, not general mass measurements.
-
Contemporary reports often favor standardized metric units rather than assay tons.
Frequently Asked Questions
-
What is a gram in terms of measurement?
-
A gram is an SI-derived unit of mass equal to one thousandth of a kilogram, commonly used to measure small masses in science, engineering, and daily life.
-
What is the US assay ton used for?
-
The US assay ton is a historical mass unit used in mining to report precious metal content on assay certificates and for contractual ore shipment calculations.
-
Why does the mass of the US assay ton vary?
-
The US assay ton's exact mass has historically differed by jurisdiction and practice, so modern use often specifies exact masses to avoid confusion.
Key Terminology
-
Gram [g]
-
An SI-derived unit of mass equal to one thousandth of a kilogram, used for measuring small masses.
-
Ton (assay) (US) [AT (US)]
-
A historical mining mass unit used to report precious metal content; its exact mass varies by jurisdiction and practice.
