About these units
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.
Kilopound (kip)
A kilopound, or kip, equals 1,000 pounds and is used primarily in structural engineering, especially in the United States. Loads, tensions, and compression forces in steel beams, concrete structures, and bridges are often expressed in kips. The kip allows engineers to avoid large numbers when expressing forces such as building loads or material stresses. In structural analysis software and construction documents, kips are ubiquitous. Despite not being a mass unit strictly speaking (it is often used as a force unit, kip-force), it remains central to American engineering practice.
