What Is This Tool?
This tool performs conversions between the troy or apothecary pound, a historical mass unit, and the dalton, an atomic mass unit used in scientific fields such as chemistry and biochemistry.
How to Use This Tool?
-
Enter the value in pounds (troy or apothecary) you wish to convert
-
Select the unit 'pound (troy or apothecary)' as the input unit
-
Choose 'dalton' as the target conversion unit
-
Click 'Convert' to get the equivalent mass value in daltons
-
Review the output and use it for your scientific or historical applications
Key Features
-
Converts pound (troy or apothecary) to dalton with a precise conversion rate
-
Supports interpretation of historical and precious-metal mass measurements
-
Facilitates molecular and atomic mass analysis in scientific research
-
Browser-based and straightforward to use
-
Useful for chemistry, pharmacology, and historical metrology contexts
Examples
-
2 pounds (troy or apothecary) equals 449545291683620000000000000 daltons
-
0.5 pound (troy or apothecary) equals 112386322920905000000000000 daltons
Common Use Cases
-
Converting historical apothecary prescriptions and pharmacopoeia records to modern units
-
Cataloguing weights of old coins and museum artifacts recorded in troy/apothecary pounds
-
Analyzing atomic and molecular masses in chemistry and physical chemistry
-
Reporting protein and peptide masses in biochemistry and proteomics
-
Describing monomer and oligomer masses in polymer science via mass spectrometry
Tips & Best Practices
-
Ensure you specify the correct historical pound variant when entering data
-
Use the conversion primarily for scientific or historical contexts due to unit obsolescence
-
Interpret large numerical results carefully because of the dalton's very small mass scale
-
Cross-check conversions when dealing with precious-metal or molecular mass data
-
Keep in mind the limitations of applying this conversion outside specialized applications
Limitations
-
The troy pound is largely obsolete and seldom employed in modern measurement
-
Dalton values are extremely large numbers due to the small size of the unit
-
Conversions are mostly relevant for historical or specialized scientific contexts
Frequently Asked Questions
-
What is a troy or apothecary pound?
-
It is a historical unit of mass equal to 12 troy ounces or exactly 373.2417216 grams, formerly used in apothecaries and precious-metal measurement.
-
What does one dalton represent?
-
One dalton is an atomic mass unit equal to 1/12 the mass of a carbon-12 atom, used for expressing atomic and molecular masses.
-
Why convert troy pounds to daltons?
-
This conversion helps translate historical and precious-metal masses into atomic-scale units for scientific research and analysis.
-
Is the troy pound still in use today?
-
No, it is largely obsolete and mainly used in historical or specialized contexts.
-
Are the resulting dalton numbers easy to handle?
-
No, due to the very small size of daltons, the converted numbers are extremely large and can be unwieldy.
Key Terminology
-
Pound (Troy or Apothecary)
-
A historical mass unit equal to 12 troy ounces or 5,760 grains, exactly 373.2417216 grams, used in apothecaries and bullion measurement.
-
Dalton (Da)
-
A unit of mass equal to 1/12 the mass of a carbon-12 atom, used to express atomic and molecular masses.
-
Troy Ounce
-
A unit of mass used in the troy system; 12 troy ounces make one troy pound.
