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




Kilogram-force second squared per meter (kgf·s²/m)


This is a derived unit combining mechanical units and force.



  • Kilogram-force (kgf): A unit of force defined as the force exerted by gravity on one kilogram of mass at standard gravity (9.80665 m/s²).



    • 1 kgf ≈ 9.80665 newtons (N).




  • The unit kgf·s²/m can be interpreted as a measure related to mechanical impedance or compliance in some physics or engineering contexts, combining force, time squared, and distance.



Breakdown:



  • Force (kgf) × Time² (s²) / Length (m)



  • It has dimensions of mass × time² / length (since 1 kgf ≈ 9.81 N = kg·m/s²)



This unit is uncommon but might appear in specific engineering or physics formulas related to dynamic systems or mechanical vibrations.
