About these units
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.
Megagram (Mg)
A megagram, equal to 1,000 kilograms, is identical in quantity to the metric ton (tonne). While "tonne" is common in daily life, Mg is preferred in engineering, environmental science, and formal scientific writing because it is unambiguous and adheres strictly to SI conventions. Megagrams are used to express masses of vehicles, construction materials, waste output, or agricultural yields in large-scale analyses. The unit is especially useful in Earth sciences, where megagram quantities describe biomass, sediment transport, or volcanic emissions.
