The 5 pages that link to Electron mass, each with the reason it gives.

• ElectronRelated: Its small but nonzero rest mass distinguishes it from massless particles.

• Bohr magnetonRelated: It appears in the denominator, setting the magneton's scale for an electron.

• Classical electron radiusRelated: The radius is inversely proportional to this mass.

• Bohr radiusRelated: It appears in the denominator of the standard Bohr-radius formula.

• Atomic unitsRelated: Setting it to one makes the electron the reference mass in this system.
