About these units
Drachma (Biblical Greek) (drachma)
The drachma, roughly 4.3 grams, served as the principal Greek silver unit for centuries. Both a mass and a monetary unit, the drachma appears extensively in ancient writings, from philosophy to commerce to biblical passages. The term originates from "a handful," linking the weight to early barter practices. Over time, it became a symbol of civic identity—different city-states minted distinct drachmas with unique iconography. Its influence survives in the name of Greece's former national currency, the drachma, reinforcing its cultural legacy.
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.
