Kilogram

The kilogram (also kilogramme) is the base unit of mass in the metric system, formally the International System of Units (SI), having the unit symbol kg. It is a widely used measure in science, engineering, and commerce worldwide, and is often simply called a kilo in everyday speech. 


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.
