About these units
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.
Muon Mass (mᵤ)
The muon is a heavier cousin of the electron, with a mass of about 1.8835316 × 10⁻²⁸ kilograms, roughly 207 times more massive than the electron. Because the muon behaves like an electron but with much greater mass, it offers unique opportunities for probing fundamental physics. Muonic atoms—where a muon replaces an electron—allow extremely precise measurements of nuclear size due to the muon's tighter orbit. Muons are also produced naturally in Earth's atmosphere from cosmic rays and are widely studied in particle accelerators. Research into muon behavior has led to major discoveries, and the muon mass continues to attract interest in tests of physics beyond the Standard Model.
