What Is This Tool?
This converter transforms values from the US assay ton, a traditional unit used in mining and assaying precious metals, into decigrams, an SI-derived unit ideal for expressing small masses with fine resolution.
How to Use This Tool?
-
Enter the mass value in ton (assay) (US) [AT (US)].
-
Select ton (assay) (US) as the starting unit and decigram [dg] as the target unit.
-
Click convert to get the equivalent mass in decigrams.
Key Features
-
Converts US assay tons (historical mining unit) to decigrams (SI mass unit).
-
Provides a standardized way to relate precious metal mass from assay certificates to modern mass units.
-
Supports applications requiring detailed mass measurement for metals and laboratory samples.
Examples
-
Convert 2 Ton (assay) (US) to Decigram: 2 × 291.6667 = 583.3334 Decigram [dg]
-
Convert 0.5 Ton (assay) (US) to Decigram: 0.5 × 291.6667 = 145.83335 Decigram [dg]
Common Use Cases
-
Reporting gold or silver concentration as ounces per assay ton on assay certificates.
-
Calculating payments or contracts for ore shipments based on metal content per assay ton.
-
Converting historical assay mass data into modern units for analysis and comparison.
-
Laboratory and analytical contexts needing precise mass measurement of precious metals.
Tips & Best Practices
-
Verify the exact assay ton definition used, as it can vary historically by jurisdiction.
-
Use decigrams for measurements requiring finer mass resolution than grams.
-
Apply this conversion when preparing data for laboratory or contractual use to ensure accuracy.
-
Be cautious with large mass values as decigram results can become very large numbers.
Limitations
-
Historical variation in the US assay ton means conversion accuracy depends on knowing the specific standard used.
-
Decigrams are small units, so conversions from large assay tons yield very large numbers that may be cumbersome.
-
This tool does not handle mass units outside of ton (assay) (US) and decigram.
Frequently Asked Questions
-
What is the US assay ton used for?
-
It is a historical mining and assaying unit for reporting precious metal content and standardizing assay sample mass.
-
Why convert ton (assay) (US) to decigram?
-
To express assay mass values in finer, SI-based units suitable for laboratory measurements and precise quantification.
-
Does the assay ton have a fixed mass?
-
No, its exact mass has historically varied by jurisdiction and practice.
Key Terminology
-
Ton (assay) (US) [AT (US)]
-
A historical mining mass unit used for defining standard sample masses in precious metal assays with varying exact masses by region.
-
Decigram (dg)
-
An SI-derived mass unit equal to one tenth of a gram, used for measuring small masses with greater precision.
