About these units
Hectogram (hg)
A hectogram equals 100 grams and is common in food markets in Italy, Greece, and parts of Latin America. Consumers often purchase cheese, cold cuts, or dry goods in hectograms because it provides a comfortable scale—neither too large nor too small. In scientific contexts, hectograms sometimes appear in hydrology, meteorology, or soil science, where medium quantities are more intuitively expressed using this unit. Though overshadowed globally by the kilogram, the hectogram survives where cultural habits align with metric logic.
Pennyweight (pwt)
The pennyweight, equal to 1/20 of a troy ounce or 1.55517384 grams, is a unit used primarily in the precious metals and jewelry industries. Its origins lie in medieval English coinage, when the weight of silver pennies provided a practical standard for small masses. Jewelers continue to use the pennyweight because many traditional pricing structures and metalworking conventions are built around troy-based subdivisions. For gold, silver, and dental alloys, the pennyweight remains easier to work with than grams due to long-established norms. Even though the metric system is now dominant scientifically, the pennyweight persists because industries tied to history—especially those involving money and precious goods—tend to maintain deeply rooted practices.
