What Is This Tool?
This converter transforms mass values from megagram (Mg), a metric unit equivalent to 1,000 kilograms, into the US assay ton (AT), a traditional mass measure used mainly in mining and precious-metal reporting.
How to Use This Tool?
-
Enter the mass value in megagrams [Mg] you want to convert
-
Select the target unit as ton (assay) (US) [AT (US)] from the options

Includes clear examples to assist with common conversion needs
Examples
-
2 Megagrams [Mg] converts to 68,571.420734694 Ton (assay) (US) [AT (US)]
-
0.5 Megagram [Mg] converts to 17,142.855183674 Ton (assay) (US) [AT (US)]
Common Use Cases
-
Reporting heavy cargo or freight mass for transport vehicles
-
Assessing precious-metal content in mining assay certificates
-
Settling contracts for ore shipments based on metal quantity per assay ton
-
Converting historical assay measurements for geological analysis
Tips & Best Practices
-
Confirm the specific assay ton definition applicable to your jurisdiction
-
Use the converter to assist with interpreting legacy assay data consistently
-
Consider modern units like grams per tonne for precise assay reporting
-
Refer to examples to ensure correct input format and expected output
Limitations
-
Assay ton units have varied historically and regionally, so values may need context clarification
-
Modern assay reports often specify exact mass units to avoid confusion
-
Straight conversions assume a standard assay ton definition and may not fit all legacy datasets
Frequently Asked Questions
-
What is a megagram (Mg)?
-
A megagram is a metric-derived unit equaling 1,000,000 grams or 1,000 kilograms, also known as the metric tonne.
-
Why does the ton (assay) (US) vary in mass?
-
The assay ton's mass has historically differed by location and practice, making explicit unit designation important to avoid ambiguity.
-
Can I use this conversion for modern precious-metal reporting?
-
While useful for historical or contract reference, modern reporting favors units like grams per tonne for clarity.
Key Terminology
-
Megagram [Mg]
-
An SI-derived mass unit equal to 1,000,000 grams or 1,000 kilograms, also called a metric tonne.
-
Ton (assay) (US) [AT (US)]
-
A traditional mining unit for measuring sample mass in precious-metal assays, historically varying by jurisdiction.
-
Assay certificate
-
A report detailing the concentration of precious metals in a sample, often expressed per assay ton.
