In this article, we will learn about the mass of an electron in kg, grams, amu and eV. We will also learn the rest mass of an electron along with some FAQs What is the Absolute Mass and Charge of an Electron ? The absolute mass of an electron is the same as its mass as mentioned above, approximately 9.10938356 × 10 -31 kg. However, the charge of an electron is -1.602176634 × 10 -19 coulombs (C). This negative charge balances with a proton’s positive charge, resulting in an atom’s overall ... The electron has mass m_e = 9.1095\times 10^ {-28} {\rm\ g}=9.1095\times 10^ {-31} {\rm\ kg} = 0.51100 {\rm\ MeV}/c^2, where c is the speed of light. See also: Electron , Electron Charge Learn about the electron mass , a fundamental constant of physics that has a value of about 9.109 × 10−31 kg or 5.486 × 10−4 Da. Find out how it is measured, calculated and related to other physical constants.
