About these units
Assarion (Biblical Roman) (assarion)
The assarion, worth 1/16 of a denarius and weighing roughly 0.25 grams, was one of the smallest Roman coins. It appears in biblical writings to illustrate humility or trivial monetary values ("Are not two sparrows sold for an assarion?"), giving cultural insight into economic metaphors of the time. As a weight, the assarion shows how finely Roman society subdivided monetary units for everyday commerce.
Atomic Mass Unit (u)
The atomic mass unit (u) is defined as exactly 1/12 the mass of a neutral carbon-12 atom, which makes it approximately 1.66053906660 × 10⁻²⁷ kilograms. This definition allows scientists to express atomic and molecular masses in a convenient, intuitive scale that aligns with the structure of the periodic table. By anchoring the unit to carbon-12, chemists and physicists gained a universal reference point that harmonizes molecular weight, relative isotopic abundance, and mass spectroscopy results. The atomic mass unit effectively normalizes the complexity of atomic masses into whole-number or near-whole-number values for most nuclei. In chemistry, u is indispensable for calculating molar masses, reaction stoichiometry, and isotopic compositions. It is also used across nuclear physics, astrophysics, and biophysics, demonstrating the universality of atomic-scale measurement.
