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.
UK Ton (Long) (ton (UK))
The British long ton equals 2,240 pounds (1,016.0469088 kilograms). Historically used throughout the British Empire, it appears frequently in naval records, early engineering documents, and historical trade ledgers. The long ton's relation to the imperial hundredweight (112 pounds × 20) makes sense within the structure of older English measurement systems. Although replaced by metric tons in the UK, it persists in maritime contexts and in interpreting historical documents. Its presence captures the complexity of pre-metric trade and the need for careful interpretation when comparing international tonnage systems.
