About these units
Muon Mass (mᵤ)
The muon is a heavier cousin of the electron, with a mass of about 1.8835316 × 10⁻²⁸ kilograms, roughly 207 times more massive than the electron. Because the muon behaves like an electron but with much greater mass, it offers unique opportunities for probing fundamental physics. Muonic atoms—where a muon replaces an electron—allow extremely precise measurements of nuclear size due to the muon's tighter orbit. Muons are also produced naturally in Earth's atmosphere from cosmic rays and are widely studied in particle accelerators. Research into muon behavior has led to major discoveries, and the muon mass continues to attract interest in tests of physics beyond the Standard Model.
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.
