What Is This Tool?
This converter transforms mass values from centigrams (cg), a metric measure used for small quantities, to scruples (apothecary) (s.ap), a historical unit once common in pharmacy and medicine. It helps users interpret and convert old apothecary measurements into modern terms.
How to Use This Tool?
-
Enter the mass value in centigrams (cg) into the input field.
-
Select scruple (apothecary) [s.ap] as the target unit for conversion.
-
Click the convert button to view the equivalent mass in scruples.
-
Use the converted value to interpret historical or pharmaceutical data.
Key Features
-
Converts between centigram and scruple (apothecary) units accurately.
-
Ideal for interpreting historical pharmaceutical and medical records.
-
Browser-based, easy to use interface for quick conversions.
-
Supports conversion of small laboratory and pharmaceutical sample masses.
Examples
-
10 cg converts to approximately 0.077161792 scruples (s.ap).
-
50 cg converts to approximately 0.38580896 scruples (s.ap).
Common Use Cases
-
Decoding old medical prescriptions that specify ingredient amounts in apothecary scruples.
-
Translating archival pharmaceutical and botanical formulations into metric units.
-
Supporting research in historical pharmacy, medicine, and alchemical studies.
-
Measuring small sample masses in pharmaceutical compounding and laboratory settings.
Tips & Best Practices
-
Double-check converted values when working with historical documents for accuracy.
-
Use the tool primarily in research or archival contexts due to unit obsolescence.
-
Be aware of possible regional variations or rounding in old apothecary measurements.
-
Ensure input values are precise, especially when dealing with small mass quantities.
Limitations
-
The apothecary scruple is mainly obsolete and suited for historical or archival use.
-
Regional historical differences and rounding can affect conversion precision.
-
Modern pharmaceutical compounding rarely uses apothecary units, limiting direct applications.
Frequently Asked Questions
-
What is a centigram?
-
A centigram is a metric unit of mass equal to one hundredth of a gram (0.01 g), commonly used for measuring small samples or precise quantities.
-
What is the scruple (apothecary) unit?
-
The scruple (apothecary) is a historical mass unit used in pharmacy, equal to about 1.296 grams, primarily useful for interpreting old medical prescriptions.
-
Why convert between centigrams and scruples?
-
Converting these units helps translate historical pharmaceutical or medical data into modern measurements for accurate analysis or reproduction.
