What Is This Tool?
This tool converts weight values from pounds, a common unit of mass in the avoirdupois system, into scruples, a historical apothecary unit primarily used in pharmacy. It helps translate modern masses into older weight systems for specialized historical or pharmaceutical research.
How to Use This Tool?
-
Enter the weight value in pounds (lbs) you want to convert.
-
Select scruple (apothecary) [s.ap] as the target unit.
-
Click the convert button to get the equivalent mass in scruples based on the conversion factor.
-

Key Features
-
Converts pounds, widely used for human body weight and retail product labeling, into apothecary scruples.
-
Supports interpretation of historical medical prescriptions and pharmaceutical texts.
-
Browser-based and easy to use for quick weight conversions between modern and historical units.
-
Accurately applies the fixed conversion rate between pounds and scruples (apothecary).
Examples
-
Convert 2 pounds to scruples to get 700 scruples (apothecary).
-
Convert 0.5 pounds to scruples to find 175 scruples (apothecary).
Common Use Cases
-
Translating historic pharmacy prescriptions and formulations into modern mass units.
-
Converting archival pharmaceutical, botanical, or alchemical recipes for analysis or reproduction.
-
Research in pharmaceutical history and archival medicine involving old mass units.
-
Studying botanical or alchemical works that use apothecary units.
Tips & Best Practices
-
Double-check input values to ensure accurate conversions between pounds and scruples.
-
Use this converter mainly for historical, archival, and research contexts due to the obsolescence of the scruple unit.
-
Cross-reference converted values with original prescription contexts when interpreting old pharmaceutical texts.
Limitations
-
The apothecary scruple is largely obsolete, so conversions have limited use in everyday measurements.
-
Slight discrepancies can occur when converting very precise modern weights due to the historical nature of the scruple.
-
The relevance of the scruple mainly pertains to historical or archival contexts.
