amu

AMU is an acronym with multiple meanings. In science, AMU most commonly refers to the atomic mass unit, also called the unified atomic mass unit.

It is a unit of mass used to express the masses of atomic-scale objects such as atoms, ions, and molecules. One atomic mass unit is defined as exactly 1/12 of the mass of a carbon-12 atom. In modern terms, 1 u equals 1.66053906660×10^-27 kilograms, and it is equivalent to one dalton (Da). The amu is a non-SI unit accepted for use with SI; it provides a convenient scale for expressing molecular masses, where the molar mass in grams per mole numerically equals the molecular mass in amu. For example, water has a molar mass of about 18 g/mol and a molecular mass of about 18 amu.

In academia and public life, AMU commonly stands for Aligarh Muslim University, a public central university located in Aligarh, Uttar Pradesh, India. Founded in the late 19th century as Muhammadan Anglo-Oriental College and renamed Aligarh Muslim University in 1920, it offers undergraduate and graduate programs across many disciplines. It is funded by the Government of India and is one of the country’s oldest and most prominent universities, with a wide alumni network and multiple campuses and centers.
