What Is This Tool?
This converter transforms values from the long ton (UK), a historical imperial mass unit, into the UK assay ton, a unit used primarily in assay laboratories and the mining industry to quantify ore and metal content.
How to Use This Tool?
-
Enter the value in ton (long) [ton (UK)] you wish to convert.
-
Select 'ton (long) [ton (UK)]' as the input unit and 'ton (assay) (UK) [AT (UK)]' as the output unit.
-
Click the convert button to obtain the equivalent value in ton (assay) (UK) [AT (UK)].
-
Use the result for assay reporting, commercial calculations, or data analysis.
Key Features
-
Converts between historical UK long ton and UK assay ton units.
-
Supports specialized contexts like mining, metallurgy, and assay reporting.
-
Facilitates interpretation of legacy trade and engineering documents.
-
Provides precise multiplication using the official conversion rate.
-
Browser-based and easy to use without installation.
Examples
-
2 ton (long) [ton (UK)] equals 62206.9536 ton (assay) (UK) [AT (UK)].
-
0.5 ton (long) [ton (UK)] converts to 15551.7384 ton (assay) (UK) [AT (UK)].
Common Use Cases
-
Recording or converting historical UK ship displacement and shipping cargo figures.
-
Translating bulk commodity weights like coal or ore from legacy British trade data.
-
Reporting and pricing ore or metal shipments using assay ton values.
-
Analyzing laboratory assay certificates showing grams or ounces per assay ton.
-
Reconciling historical assay records with modern units during resource estimation.
Tips & Best Practices
-
Always confirm the context to ensure the assay ton unit is appropriate for your calculation.
-
Refer to legacy documentation carefully as assay ton definitions may vary historically.
-
Use the official conversion factor exactly as provided for accuracy in reporting.
-
Apply this conversion primarily for assay and metallurgical calculations rather than general weight conversions.
Limitations
-
The assay ton is designed specifically for ore and metal assay contexts and is not a general-purpose weight unit.
-
There are historical variations in assay ton definitions that require careful interpretation.
-
Direct substitution of assay ton for long ton in unrelated calculations may lead to errors.
Frequently Asked Questions
-
What is the primary use of the UK assay ton?
-
The UK assay ton is mainly used in assaying to report the quantity of ore or metal for analytical and commercial purposes.
-
How does the long ton compare to the assay ton?
-
The long ton is a large imperial unit of mass historically used in the UK, while the assay ton is a specialized unit used specifically in assay reporting and differs significantly in scale.
-
Can I use this conversion for general shipping weight calculations?
-
No, this conversion is intended for assay and metallurgical contexts, and using the assay ton outside those fields may not be appropriate.
Key Terminology
-
Ton (long) [ton (UK)]
-
An imperial mass unit equal to 2,240 avoirdupois pounds, used historically in the UK and maritime contexts.
-
Ton (assay) (UK) [AT (UK)]
-
A traditional industry-specific unit used in assay practice to quantify ore or metal mass for analytical and commercial calculations.
-
Conversion Rate
