About these units
US Ton (Short) (ton (US))
The US short ton equals 2,000 pounds (907.18474 kilograms) and is widely used in American industry, shipping, mining, agriculture, and engineering. Its definition at 2,000 pounds makes calculations convenient within the imperial system but creates potential confusion internationally, where the metric ton is standard. In markets such as coal, steel, and chemicals, contracts often specify the unit explicitly to avoid ambiguity. The US ton's role in commercial regulation, freight classification, and manufacturing ensures that it remains deeply embedded in American economic activity despite the global rise of the metric system.
Exagram (Eg)
An exagram, equal to 10¹⁵ kilograms, is used to describe masses of planets, moons, and extremely large terrestrial reservoirs (e.g., total mass of Earth's atmosphere ≈ 5 Eg). Because of its enormous scale, the exagram rarely appears outside astrophysics or large-scale geophysics. When used, however, it provides a powerful sense of magnitude—allowing scientists to describe Earth systems at the grandest scales with simple, comprehensible numbers.
