About these units
Gram (g)
The gram is one-thousandth of a kilogram and is widely used in everyday life for measuring food, medicines, small components, and scientific samples. Its scale is convenient for objects too light to measure in kilograms yet too heavy for milligrams. Chemists, biologists, and lab technicians rely heavily on grams to quantify reagents, biological specimens, powders, and liquids. The gram appears frequently in nutrition labels, recipes, and manufacturing specifications. As a metric unit, the gram benefits from simplicity and ease of conversion—just move the decimal to reach milligrams or kilograms. Its intuitive scale makes it one of the most universally recognized units in the world.
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.
