In physics, proton is a subatomic particle. It is made up of current quarks and is denoted by p or p+. Proton location is inside the nucleus. The charge of the proton is positive that is +1e elementary charge. The proton mass is slightly less than the neutron mass. Mass of proton can be measured using the units kg, MeV/c, and u (AMU).
Mass of Proton
Mass of the proton is the sum of the mass of current quarks and the binding gluons. The mass of the proton is-
Proton mass mp = 1.672621898(21)×10−27 Kg
Mass of proton is higher than the mass of electron
Mass of Proton in other Units
The mass of the proton can be expressed in alternative units like – proton mass AMU, the mass of the proton in kg, proton mass MeV. The table given below comprises the value of proton mass and corresponding units.
| Proton mass | Value |
| Mass of the proton in kg | 1.672621898(21)×10−27 kg |
| Mass of the proton in grams | 1.672621898(21)×10−24 g |
| Mass of proton in AMU | 1.007276466879(91) u |
| Proton mass in MeV | 938.2720813(58) MeV/c2 |
