About these units
Didrachma (Biblical Greek) (didrachma)
The didrachma, weighing around 8.5–9 grams, represented two drachmas. It appears in Greek, Roman, and biblical texts, often as a common temple tax or civic fee amount. Its moderate size made it practical for everyday transactions, bridging smaller denominations and larger, more valuable coins such as tetradrachms. The didrachma's consistent appearance in multiple cultures shows how interconnected the ancient Mediterranean economies were.
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.
