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.
Quintal (Metric) (cwt (m))
The metric quintal, equal to 100 kilograms, is commonly used in agriculture for measuring harvest yields, livestock feed, and bulk commodities such as grains, sugar, and potatoes. Its simplicity makes it popular in countries with strong agricultural sectors. Farmers, traders, and cooperatives find the quintal more intuitive for medium-sized loads than kilograms or metric tons. Though not an SI unit, it remains deeply embedded in agricultural commerce throughout Europe, Asia, and Latin America.
