See "Electronvolt: Mass". – Řídící. Oct 18, 2013 at 22:36. Add a comment. Strictly speaking it's a unit of energy. But using m = E c2 m = E c 2, you can convert energy into mass. Operating, we get 1eV 2 = 1.78 ⋅10−36kg 1 2 = 1.78 ⋅ 10 − 36. (The 2 2 is usually ommited.) Add a comment. The mass of an electron (m_e) is a fundamental constant of nature and a very small number. It is so small that its mass is usually expressed in units of electron volts (eV) instead of grams or kilograms. .

Now a volt is a joule per coulomb, so an electron volt is one electric charge times one, or approx 1.6 x 10 -19 joules (J). Astronomers use electron volts to measure the energy of electromagnetic .

So when someone tells you the mass of the electron is 0.511 MeV, don't panic. Just place a mental over c 2 in the statement and all will be well. Table of Conversions to MKS. ENERGY MOMENTUM MASS 1 eV = 1.609 x 10-19 J 1 eV/c = 5.36 x 10-28 kg-m/s 1 eV/c 2 = 1.79 x 10-36 kg 1 keV = 1.609 x 10-16 J 1 keV/c = 5 .

The electron rest mass (symbol: me) 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. It has a value of about 9.109×10−31 kilograms or about 5.486×10−4 daltons, equivalent to an energy of about 8.187×10−14 joules or about 0.5110 MeV.The energy of a particle (mass m moving with momentum p) is given by. E2 = (pc)2 + (mc2)2. or: E2 = p2c2 + m2c4. You may have noticed that particle physicists often refer to particle masses and momenta in electron-volt energy units of MeV or GeV. They can do this because the speed of light, c, is a defined constant and can be used as a unit .
