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.
Poundal
The poundal (pdl) is a unit of force in the foot-pound-second (FPS) system, defined as the force required to accelerate a one-pound mass at a rate of one foot per second squared.
History/Origin
The poundal was introduced in the 19th century as part of the FPS system of units, primarily used in engineering and physics before the widespread adoption of the SI system. It was designed to provide a consistent force unit based on imperial units.
Current Use
Today, the poundal is largely obsolete and rarely used outside of historical or specialized engineering contexts. It is mainly referenced for educational purposes or in discussions of imperial units, with the SI unit of force (newton) being the standard.
