About these units
Electron Mass (mₑ)
The electron mass, approximately 9.10938356 × 10⁻³¹ kilograms, is a fundamental constant of nature and a cornerstone of atomic physics. Because electrons determine atomic structure, bonding, and electrical properties, their mass plays a crucial role in chemistry and solid-state physics. The smallness of the electron mass allows quantum phenomena to dominate electron behavior, enabling orbitals, tunneling, and band structures in materials. Electrons' tiny mass also affects how atoms interact with electromagnetic radiation, influencing spectral lines and optical properties. In particle physics, the electron mass is one of the defining parameters of the Standard Model, impacting interactions across quantum electrodynamics (QED) and beyond.
Kilogram-force Second/Meter (kgf·s²/m)
This unusual unit represents a derived inertial mass-like quantity used in older engineering contexts based on gravitational force units rather than pure mass. One kilogram-force is the force exerted by gravity on a mass of one kilogram under standard gravity. When combined with s²/m, this creates a pseudo-mass unit used in engineering calculations involving dynamic systems. Although rarely used today, kgf·s²/m illustrates a transitional phase in engineering where gravitational and inertial concepts were intermixed before SI units standardized distinctions between mass and force.
