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




Ton (Assay) (US) [AT (US)]


The assay ton (AT) is a specialized unit of weight used in the mining and precious metals industries in the United States. It is primarily used to measure ore quantities for assaying, which is the process of analyzing the metal content of ore samples.


One assay ton equals 29.1667 pounds (about 13.23 kilograms), which is different from the standard short ton (2,000 pounds). This smaller ton unit allows for more precise measurements in evaluating the value of ore deposits.


The assay ton helps miners and metallurgists accurately calculate the concentration of valuable metals like gold and silver in ores.
