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.
Planck Mass (mₕ)
The Planck mass, approximately 2.176434 × 10⁻⁸ kilograms, occupies a unique position in theoretical physics. Unlike particle masses, it is derived entirely from fundamental constants—Planck's constant, Newton's gravitational constant, and the speed of light. The Planck mass represents a mass scale where quantum mechanical and gravitational effects become comparable. Although enormous relative to subatomic particles (roughly the mass of a dust grain), it is considered "natural" in that it emerges from pure physics rather than empirical observation. In theoretical studies of black holes, quantum gravity, string theory, and early-universe cosmology, the Planck mass marks a boundary beyond which existing models require unification. It is a conceptual rather than practical unit, yet it provides a profound insight into the structure of physical law.
