About these units
Quadrans (Biblical Roman) (quadrans)
The quadrans, worth 1/4 of an as, weighed around 3 grams, typically made of bronze rather than silver. It served the Roman lower classes for everyday purchases—food, small household items, and public baths. In biblical passages, the quadrans symbolizes poverty and small generosity, anchoring theological teachings in real economic terms.
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.
