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.
Kilogram (kg)
The kilogram is the base unit of mass in the SI system and the only SI unit defined directly by a fundamental constant rather than a physical object. Originally, its definition was tied to a platinum–iridium artifact stored in France—the famous "International Prototype Kilogram." Over time, tiny mass changes in the prototype and its official copies created difficulties for high-precision science. In 2019, the kilogram was redefined using Planck's constant, linking mass to the laws of quantum physics through the Kibble balance. This innovation ensures universality, stability, and reproducibility across the world. The kilogram is central to commerce, science, engineering, and every quantitative field dealing with matter. Its decimal relationships with other metric units (grams, milligrams, tons) make it universally convenient. From groceries to spacecraft mass budgets, the kilogram anchors modern mass measurement.
