About these units
Didrachma (Biblical Greek) (didrachma)
The didrachma, weighing around 8.5–9 grams, represented two drachmas. It appears in Greek, Roman, and biblical texts, often as a common temple tax or civic fee amount. Its moderate size made it practical for everyday transactions, bridging smaller denominations and larger, more valuable coins such as tetradrachms. The didrachma's consistent appearance in multiple cultures shows how interconnected the ancient Mediterranean economies were.
Proton Mass (mₕ (p))
The proton mass, approximately 1.67262192369 × 10⁻²⁷ kilograms, is central to chemistry, nuclear physics, and cosmology. Protons, along with neutrons, form the nuclei of atoms and therefore compose most of the mass of ordinary matter. The proton mass arises from the strong nuclear force and the dynamics of quarks and gluons within quantum chromodynamics (QCD). Interestingly, most of the proton's mass is not from its constituent quarks but from the energy stored in the strong force. Understanding the proton mass helps scientists explore nuclear stability, binding energies, and stellar nucleosynthesis—the processes that form elements inside stars.
