The Atomic Mass unit (amu), or Dalton (Da) or, sometimes, universal mass unit, is a unit of mass used to express atomic and molecular masses. It is the approximate mass of a hydrogen atom, a proton, or a neutron.
. 1 u = 1/NA gram = 1/ (1000 NA) kg (where NA is Avogadro's number) 1 u = 1.660538782(83)×10−27 kg = 931.494027(23) MeV/c2
It is a unit of mass used to express atomic and molecular weights, equal to one-twelfth of the mass of an atom of carbon-12. It is equal to approximately 1.66 x 10^-27 kg.

∙ 11y ago1 amu (atomic mass unit) is equal to 1.6605 X 10-27 kg. It is useful because you can use it to calculate the amount of grams in a certain amount of moles of an atom. For example, if you look at the Periodic Table, carbon's atomic weight is 12 amu. This means that 1 mole of carbon weights 12 grams. Said in another way, 12 amu of carbon is 12 grams of carbon per mole.
