About these units
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.
Teragram (Tg)
A teragram equals 1,000 gigagrams, or 10⁹ kilograms. It is widely used in climatology, atmospheric science, and ecology to describe the mass of carbon, nitrogen, methane, or other substances exchanged annually between Earth's systems. For example, global carbon fluxes—movement of carbon between oceans, atmosphere, and biosphere—are typically measured in teragrams. Volcanoes, wildfires, and anthropogenic emissions often release substances on this scale. Tg-level measurements give researchers insight into the stability, sustainability, and long-term trends of Earth's ecosystems.
