About these units
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.
Scruple (Apothecary) (s.ap)
The scruple is an old apothecary unit equal to 20 grains or 1.2959782 grams, originating in ancient Greek and Roman medicine. Apothecaries used scruples for compounding herbal remedies, powders, and tinctures long before standardized metric systems were adopted. Its size made it ideal for preparing early pharmaceuticals where doses needed to be accurate but not excessively granular. Over centuries, the scruple appeared in medical recipes, early scientific writings, and even medieval charms and remedies. Although obsolete today, replaced by milligrams and grams, the scruple is vital for historians studying early medical texts, pharmacy records, and classical-era scientific practices.
