Electron Mass (Rest)


The rest mass of an electron is the intrinsic mass of an electron when it is at rest (not moving relative to an observer).


Its value is approximately 9.109 × 10⁻³¹ kilograms (or about 0.511 MeV/c² in energy units).


This tiny mass is fundamental to atomic and particle physics, influencing how electrons behave in atoms and electric currents.


Summary:



  • Rest mass ≈ 9.109 × 10⁻³¹ kg



  • Equivalent to about 0.511 MeV/c²



  • Fundamental property of the electron in physics




Grain [gr]


The grain (gr) is one of the oldest units of mass, traditionally used in various weight systems including troy, apothecary, and avoirdupois.


One grain is defined as exactly 64.79891 milligrams (0.0648 grams). It was originally based on the weight of a single grain of barley or wheat.


Grains are still commonly used today to measure small quantities such as the weight of bullets, arrows, and some pharmaceuticals.


Summary:



  • 1 grain = 64.79891 milligrams (0.0648 grams)



  • Used in troy, apothecary, and avoirdupois systems



  • Common in ammunition and medicine measurements
