0.510 998 950 69 (16) MeV [4] In particle physics , the electron mass (symbol: m e ) is the mass of a stationary electron , also known as the invariant mass of the electron. It is one of the fundamental constants of physics .
MeV and meV are multiples and submultiples of the electron volt unit, (eV), referring to: 1 MeV , 1 mega electronvolt = 1,000,000 eV, and 1 meV , 1 milli electronvolt = 0.001 eV.

Smartwatches are a hot-ticket gift over the holidays, but a new study might have you rethink how you strap the device to your wrist in the future.
In physics, natural unit systems are measurement systems for which selected physical constants have been set to 1 through nondimensionalization of physical units.For example, the speed of light c may be set to 1, and it may then be omitted, equating mass and energy directly E = m rather than using c as a conversion factor in the typical mass–energy equivalence equation E = mc 2.
