What Is This Tool?
This tool converts weight values from ton (assay) (UK) [AT (UK)], a unit used in assaying ore and metals, into carat [car, ct], a gemstone mass measurement. It is designed to help users translate specialized assay reporting units into fine gemstone mass units used in jewelry and precious metals.
How to Use This Tool?
-
Enter the quantity in ton (assay) (UK) you wish to convert
-
Select carat as the target unit
-
Click convert to see the corresponding value in carats
Key Features
-
Supports conversion between ton (assay) (UK) and carat units
-
Accurate translation of industry-specific mass measurements
-
Useful for mining, assaying, jewelry trade, and gem certification
-
Simple and browser-based interface for quick calculations
Examples
-
2 Ton (assay) (UK) [AT (UK)] = 326.6666666666 Carat [car, ct]
-
0.5 Ton (assay) (UK) [AT (UK)] = 81.66666666665 Carat [car, ct]
Common Use Cases
-
Reporting quantities of gold and silver in assay certificates
-
Pricing and calculating payable metal content in ore shipments
-
Interpreting historical assay data for resource estimation
-
Weighing and pricing gemstones in jewelry trade
-
Recording pearl weights on gemological certificates
-
Measuring small samples during jewelry manufacturing
Tips & Best Practices
-
Ensure units are not confused with other ton measurements like long ton or metric tonne
-
Use this tool for converting assay ton values to gemstone mass units accurately
-
Interpret large carat results carefully in the context of assay data
-
Double-check assay ton values before conversion for accuracy
Limitations
-
Ton (assay) (UK) differs from other ton units, so conversions require care
-
Carat is intended for small gemstone weights and may yield large numbers when converting from assay tons
-
The tool does not convert between unrelated weight units outside assay ton and carat
Frequently Asked Questions
-
What is a ton (assay) (UK) used for?
-
It is a traditional unit used in assaying to report ore or metal quantities for analytical and commercial purposes.
-
What does one carat represent?
-
One carat is a unit of mass commonly used for gemstones and pearls, exactly equal to 200 milligrams.
-
Can I use this tool to convert other types of tons?
-
No, this tool specifically converts ton (assay) (UK), which is distinct from long ton, short ton, or metric tonne.
Key Terminology
-
Ton (assay) (UK) [AT (UK)]
-
A conventional unit used in assaying to report quantities of ore or metals, distinct from other ton units.
-
Carat [car, ct]
-
A unit of mass equal to 200 milligrams, used mainly for gemstones and pearls.
