Convert proton mass to kg
Proton Mass
The proton mass (mp) is the rest mass of a proton, equal to approximately 1.67262 × 10⁻²⁷ kilograms or 938.272 MeV/c². It is approximately 1,836 times greater than the electron rest mass and is close to, but slightly less than, the neutron mass. The proton mass is a fundamental constant in nuclear and particle physics and plays a central role in determining atomic masses and nuclear binding energies.
