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.
Nanogram (ng)
A nanogram equals 10⁻⁹ grams and is widely used across chemistry, toxicology, pharmaceuticals, and material science. Quantities such as trace contaminants, allergens, pesticides, or drug residues often fall in the nanogram range. In medicine, nanogram-per-liter concentrations are standard in blood tests, especially for cardiac markers like troponin, where even tiny amounts can indicate severe physiological conditions. Nanogram quantities are also important in environmental regulation and forensic science. The nanogram unit illustrates the power of modern analytical tools that can detect vanishingly small quantities with profound real-world implications.
