Browser-based and easy to use with no installation needed
Examples
-
2 scruples (apothecary) equal approximately 1.56092115168342×10²⁴ daltons
-
0.5 scruple (apothecary) converts to about 3.90230287920855×10²³ daltons
Common Use Cases
-
Interpreting old pharmaceutical prescriptions that use apothecary measurements
-
Converting archival botanical and alchemical formulations for modern analysis
-
Reporting atomic and molecular masses in chemistry and molecular biology
-
Analyzing protein and peptide masses in proteomics
-
Studying monomer and oligomer masses in polymer science
Tips & Best Practices
-
Ensure correct input of scruple (apothecary) values from historic documents
-
Use scientific notation to handle large dalton numbers efficiently
-
Cross-check conversions when integrating archival and modern data
-
Be aware of the scruple's historical variations when interpreting results
Limitations
-
The scruple (apothecary) is a historical unit with possible mass variations depending on standards
-
Conversion to daltons results in extremely large figures requiring scientific notation
-
Precision may be affected by the historical nature of the scruple unit and numerical representation
Frequently Asked Questions
-
What is a scruple (apothecary)?
-
A scruple (apothecary) is an old unit of mass used in pharmacy and medicine, defined as 20 grains or approximately 1.296 grams, primarily used in historical pharmaceutical contexts.
-
What does the dalton measure?
-
The dalton, also called the unified atomic mass unit, measures mass at the atomic or molecular scale and is defined as 1/12 the mass of a carbon-12 atom.
-
Why convert scruples to daltons?
-
Converting scruples to daltons helps translate historical pharmaceutical masses into atomic mass units, facilitating modern scientific analysis of archival data.
Key Terminology
-
Scruple (apothecary)
-
A historical mass unit in pharmacy equal to 20 grains or roughly 1.296 grams, used for dosages and prescriptions.
-
Dalton
-
Also known as unified atomic mass unit, a mass unit used to express atomic and molecular weights, defined as 1/12 the mass of carbon-12.
-
Grain
-
A traditional unit of mass, used as a base measure in the apothecaries' weight system, where 1 scruple equals 20 grains.
