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.
Didrachma (Biblical Greek) (didrachma)
The didrachma, weighing around 8.5–9 grams, represented two drachmas. It appears in Greek, Roman, and biblical texts, often as a common temple tax or civic fee amount. Its moderate size made it practical for everyday transactions, bridging smaller denominations and larger, more valuable coins such as tetradrachms. The didrachma's consistent appearance in multiple cultures shows how interconnected the ancient Mediterranean economies were.
