Common Use Cases
-
Reporting precious metal content in assay certificates using historic mass units
-
Calculating contractual payments for ore shipments based on assay ton measurements
-
Converting old pharmaceutical formulations from apothecary units to metric equivalents
-
Translating archival mining assay data into pharmaceutical mass contexts for research
Tips & Best Practices
-
Verify the historical context of ton (assay) due to jurisdictional variations
-
Use this tool primarily for archival, historical, or analytical applications
-
Cross-check conversions with original assay certificates or medical documents
Limitations

The apothecary scruple is not commonly used in modern pharmaceutical practices
-
Exact conversions may not apply universally because of legacy unit variations
Frequently Asked Questions
-
What is a ton (assay) (US)?
-
It is a historical unit used in mining and assaying to report precious metal content, with exact mass differing by region and practice.
-
Why convert to scruple (apothecary)?
-
To interpret older pharmaceutical texts and convert historical medicine measures into modern mass units.
-
Is the apothecary scruple still used today?
-
No, it mainly serves historical and archival purposes rather than modern pharmaceutical applications.

-
A historical mass unit used chiefly in mining to define sample mass for reporting precious metal content, with mass varying by jurisdiction.
-
