About these units

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.

Atomic Mass Unit (u)

The atomic mass unit (u) is defined as exactly 1/12 the mass of a neutral carbon-12 atom, which makes it approximately 1.66053906660 × 10⁻²⁷ kilograms. This definition allows scientists to express atomic and molecular masses in a convenient, intuitive scale that aligns with the structure of the periodic table. By anchoring the unit to carbon-12, chemists and physicists gained a universal reference point that harmonizes molecular weight, relative isotopic abundance, and mass spectroscopy results. The atomic mass unit effectively normalizes the complexity of atomic masses into whole-number or near-whole-number values for most nuclei. In chemistry, u is indispensable for calculating molar masses, reaction stoichiometry, and isotopic compositions. It is also used across nuclear physics, astrophysics, and biophysics, demonstrating the universality of atomic-scale measurement.
