About Proton Mass (mp)
The proton mass is the rest mass of a proton, approximately 1.673 × 10⁻²⁷ kilograms or about 938.3 MeV/c².
mp ≈ 1,836 × mₑ ≈ 1.00728 u. About 0.1% heavier than a neutron.
To convert proton masses to kg: multiply by 1.67262192369 × 10⁻²⁷.
Nuclear energy calculations, radiation therapy dosimetry, and proton beam therapy for cancer.
A proton's mass is mostly from the kinetic energy of quarks and gluons (via E=mc²), not from the quark masses themselves (~1%).
Assuming quarks make up most of the proton's mass — quarks contribute only ~1%. The rest is binding energy.
The proton:electron mass ratio (1,836:1) is a fundamental number in physics. It determines atomic structure.
