Mass of the proton is the sum of the mass of current quarks and the binding gluons. proton mass in u: Numerical value: 1.007 276 466 621 u : Standard uncertainty: 0.000 000 000 053 u : Relative standard uncertainty: 5.3 x 10-11: Concise form 1.007 276 466 621(53) u : Click here for correlation coefficient of this constant with other constants In quantum chromodynamics, the modern theory of the nuclear force, most of the mass of protons and neutrons is explained by special relativity. The mass of the proton is-Proton mass m p = 1.672621898(21)×10 −27 Kg. The extra energy of the quarks and gluons in a region within a proton, as compared to the rest energy of the quarks alone in the QCD vacuum, accounts for almost 99% of the mass. The mass of the proton can be expressed in alternative units … Mass Of Proton In Other Units.

Mass of proton can be measured using the units kg, MeV/c, and u (AMU).

The mass of a proton is about 80–100 times greater than the sum of the rest masses of the quarks that make it up, while the gluons have zero rest mass. Mass of proton is higher than the mass of electron. The mass of the proton, proton mass, is 1.672 621 637 (83) x 10 -27 kg, or 938.272013 (23) MeV/c 2, or 1.007 276 466 77 (10) u (that’s unified atomic … Mass Of Proton. The rest mass of a proton is, thus, the invariant mass of the system of moving quarks and gluons that make up the particle, and, in such systems, even the energy of massless particles is still measured as part of the rest mass of the system.
