It's 1/12 of the mass of the 12C atom which is about (1.66*10-27 kgr)
People refer to it sometimes as 'Dalton -an eponym-' or 'amu - an acronym for sure-'

What is one twelfth of the mass of the carbon 12 atom?
the answer is the atomic mass unit
Is the mass of one electron equal the the mass of one atomic mass unit?
Since "amu" stands for "atomic mass unit" ... maybe. "mass unit" is kind of a meaningless phrase; it could refer to grams, kilograms, slugs, or whatever.
What unit of measure is used to measure atomic weight?
expressed in unified atomic mass unit, amuHowever, for practical purposes in the laboratory the relative atomic mass is used so the unit would be gram. (Relative atomic mass compares the mass of all elements to that of the carbon-12 isotope taken as exactly 12)
Atomic mass unit is equal to what?
Unified atomic mass unit, a small unit of mass used to express atomic and molecular masses. The atomic mass unit is equal to one-twelfth the mass of a carbon-12 atom or 1,660538921(73)×10−27 kg.
What is unit for atomic masses?
Atomic mass is a mass, the SI units of mass are kg. The atomic mass unit is equal to one-twelfth the mass of a carbon-12 atom or 1,660538921(73)×10−27 kg. Atomic mass unit is recognized now as a non-SI unit.
An atomic weight unit is the mass of one?
The atomic weight unit is 1/12 from the atomic mass of isotope 12C.
What is one twelfth of the mass of the carbon 12 atom?
the answer is the atomic mass unit
What is the difference between atomic mass and relative atomic mass?
Atomic mass is the measure of a mass of one atom in relation to 1/12 mass of Carbon 12 atom and measured in atomic mass unit(amu) or Dalton unit or grams/mol.Relative atomic mass is also the relative mass but does not have a unit but a ratio number.
The unit for atomic mass?
"It is defined as one twelfth of the rest mass of an unbound atom of carbon-12 in its nuclear and electronic ground state..." (Wikipedia, atomic mass unit, retrieved 2011-01-19). An atomic mass unit is approximately the mass of a neutron, or of a proton.
Is it true that the mass of a proton is about one atomic mass unit?
no

What is the mass in atomic mass unit of one fluorine atom?
19.0
What is the standard on which the amu is made?
The atomic mass unit uses carbon-12 as a standard. The atomic mass unit is one twelfth of the mass of one atom of the isotope carbon-12.
One atomic mass unit equals 931 MeV?
The atomic mass unit is equal to 931,494 061(21) eV/c2.
