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.
Kiloton (Metric) (kt)
A kiloton, equal to 1,000 metric tons, is used in large-scale industrial, geological, and agricultural contexts. However, the term is better known for expressing explosive yields, particularly of nuclear weapons. Scientists estimate the energy release of explosions by comparing them to the detonation of 1,000 tons of TNT. For example, the Hiroshima bomb had a yield of about 15 kilotons. Outside military contexts, kilotons appear in discussions of carbon emissions, waste production, and global resource extraction. They provide a manageable scale for describing quantities too large for tons but not yet at the megaton level.
