What Is This Tool?
This tool converts weight from stone (UK), an imperial unit commonly used for human body weight, to the historical US assay ton used in mining and assaying precious metals. It helps interpret and compare measurements between traditional British units and assay weights relevant in mining contexts.
How to Use This Tool?
-
Enter the weight value in stone (UK) units into the input field
-
Select stone (UK) as the source unit and ton (assay) (US) [AT (US)] as the target unit
-
Click the convert button to see the equivalent value in assay tons
-
Use the results for interpreting historical data or mining-related applications
Key Features
-
Converts stone (UK) to ton (assay) (US) [AT (US)] based on defined conversion rates
-
Suitable for mining, metallurgy, and historical assay data analysis
-
Easy-to-use online interface for straightforward unit conversion
-
Supports traditional and niche unit conversions relevant in specific industries
Examples
-
2 stone (UK) converts to 435.4486254344 ton (assay) (US) [AT (US)]
-
0.5 stone (UK) converts to 108.8621563586 ton (assay) (US) [AT (US)]
Common Use Cases
-
Reporting personal body weight in traditional British units
-
Interpreting precious metal concentrations on assay certificates
-
Conducting historical assay data conversion for resource estimation
-
Supporting mining contract settlements involving metal content per assay ton
Tips & Best Practices
-
Confirm the context of your data to ensure the conversion is relevant
-
Use this tool mainly for historical or analytical purposes involving assay weights
-
Cross-check modern assay reports which might use grams per tonne or other standardized units
-
Remember that the assay ton value can vary by jurisdiction, so verify exact definitions when necessary
Limitations
-
The ton (assay) (US) mass varies depending on historic and regional practices
-
Stone (UK) is mainly used for measuring human body mass, so conversions are specialized
-
Modern assay reporting prefers more standardized units, limiting this conversion's practical use
Frequently Asked Questions
-
What is a stone (UK) unit used for?
-
The stone (UK) is an imperial unit used mainly in the UK and Ireland to express human body weight, as well as in some traditional sports and agricultural contexts.
-
Why is the ton (assay) (US) considered a historical unit?
-
Because its exact mass has varied across jurisdictions and practices in mining and assaying, leading to a preference for modern, explicit mass units in current reporting.
-
When should I convert stone (UK) to ton (assay) (US)?
-
When analyzing or comparing traditional UK mass measurements with historical assay weights in mining, metallurgy, or related contract settlements.
Key Terminology
-
Stone (UK)
-
An imperial unit of mass equal to 14 avoirdupois pounds (6.35029318 kg), commonly used in the UK and Ireland to measure human body weight.
-
Ton (assay) (US) [AT (US)]
-
A historical mining and assaying unit representing the sample mass for precious metals, with varying exact mass depending on jurisdiction and practice.
