Pound (Troy Or Apothecary)
A pound (troy or apothecary) is a unit of weight used primarily for precious metals and gemstones, equivalent to 12 ounces or approximately 373 grams.
History/Origin
The troy pound originated in the medieval French town of Troyes, historically used in the trade of precious metals and gemstones. The apothecary pound was used in pharmacy for weighing medicines and ingredients. Both units have roots in medieval European systems of measurement.
Current Use
The troy pound is still used in the precious metals industry, especially for gold, silver, and gemstones. The apothecary pound is largely obsolete but may still be referenced in historical contexts or traditional practices.
Atomic Mass Unit
The atomic mass unit (u) is a standard unit of mass used to express atomic and molecular weights, defined as one twelfth of the mass of a carbon-12 atom.
History/Origin
The atomic mass unit was introduced in the early 20th century to provide a convenient scale for atomic weights. It was originally based on the mass of hydrogen but was later standardized to be one twelfth of the mass of a carbon-12 atom, which was adopted as a reference in 1961 by the IUPAC.
Current Use
The atomic mass unit is widely used in chemistry and physics to express atomic and molecular masses, facilitating calculations in molecular chemistry, nuclear physics, and related fields.
