Pennyweight
The pennyweight (pwt) is a unit of weight traditionally used in measuring precious metals and gemstones, equivalent to 1/20 of a troy ounce or 1.555 grams.
History/Origin
Originating in the medieval period, the pennyweight was used in the troy weight system for weighing gold and silver, especially in the jewelry and precious metals industries. Its use has persisted in certain regions and industries for historical and practical reasons.
Current Use
Today, the pennyweight is primarily used in the jewelry trade and precious metals markets to specify weights of gold, silver, and gemstones, especially in the United States and in contexts where precise measurement of small quantities is required.
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.
