About these units
Pound (lb)
The pound is a traditional unit of mass widely used in the United States and, to a lesser extent, in the United Kingdom. Defined as exactly 0.45359237 kilograms, the pound evolved from medieval English systems that themselves descended from Roman and Carolingian traditions. The pound is central to commerce, engineering, food measurement, and body weight scales in the US. Its widespread cultural presence makes it deeply familiar even in contexts where metric units dominate. Because the pound is part of a non-decimal system, subdivisions such as ounces (1/16 pound) introduce complexity, yet this structure persists due to tradition and embedded industrial standards. In engineering, the pound often appears alongside pound-force, making careful distinction between mass and force essential.
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.
