About these units
Dalton (Da)
The Dalton is numerically identical to 1 atomic mass unit and is commonly used in biochemistry and molecular biology, especially for expressing the masses of proteins, peptides, and macromolecules. While "u" is often preferred in physics and chemistry, the Dalton became the standard in biological sciences because it fits neatly into descriptions of amino acids, nucleotides, and biomolecular complexes. For example, a typical protein may have a mass of 50 kilodaltons (kDa). The adoption of the Dalton helped unify communication across genomics, proteomics, and structural biology. As molecular biology expands into nanotechnology and synthetic biology, the Dalton remains a central unit for describing the building blocks of life.
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.
