About these units
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.
Slug (slug)
The slug is a unit of mass in the English engineering system, defined such that a slug accelerated at 1 ft/s² experiences a force of 1 pound-force. Numerically, a slug is about 14.5939 kilograms. The slug resolves confusion between mass and force in imperial units by clearly separating pounds-force (lbf) from pounds-mass (lb). In dynamics problems involving Newton's laws, slugs provide a consistent mass measurement within the imperial framework. Although uncommon outside engineering physics education, the slug plays an important conceptual role in bridging imperial and SI thinking.
