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.
Exagram
An exagram (Eg) is a unit of mass equal to 10^18 grams, used to measure extremely large quantities of mass.
History/Origin
The exagram is a relatively recent addition to the metric system, introduced to facilitate the measurement of very large masses in scientific and industrial contexts, aligning with the SI prefixes for large units.
Current Use
Exagrams are primarily used in scientific research, astronomy, and large-scale industrial applications to quantify massive amounts of material or celestial bodies.
