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.
Picogram (pg)
A picogram, or 10⁻¹² grams, is widely used in molecular biology, biochemistry, and medicine. Hormones, signaling molecules, and certain viruses fall within the picogram mass range. Laboratories often quantify DNA or RNA using picograms, especially in single-cell analysis. Cellular processes frequently involve minuscule quantities of molecules, so picogram measurements allow researchers to study gene expression, protein synthesis, and chemical reactions with extreme accuracy. Diagnostic tests—such as those for biomarkers in blood—often require detection at picogram per milliliter concentrations. The picogram is a crucial bridge between the molecular scale and measurable laboratory practice, enabling breakthroughs in medical diagnostics and biotechnology.
