About these units
Pound (Troy) (lb t)
The troy pound, equal to 12 troy ounces or 373.2417216 grams, is used almost exclusively in the precious metals trade. Unlike the avoirdupois pound used for everyday goods (16 ounces), the troy pound is optimized for precious materials such as gold, silver, and platinum. This system's origins trace back to medieval trade fairs in Troyes, France, a major commercial hub. Merchants needed a consistent unit to prevent fraud and facilitate international trading, especially for valuable metals. Today, although rarely encountered by the general public, the troy pound remains fundamental in metals pricing, refining, and numismatics. It provides continuity in a highly traditional economic sector where consistency over centuries is crucial.
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.
