The atomic mass unit, often abbreviated as amu, is a unit of mass used to express atomic and molecular weights. It is defined as precisely 1/12 the mass of an unbound neutral atom of carbon-12 in its nuclear and electronic ground state, which is approximately 1.66 x 10^-27 kilograms. This unit is used because it makes it easier to work with measurements at the atomic level, where using kilograms would result in very small numbers.
