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.
1 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.
One-twelfth the mass of a carbon-12 atom or 1,660538921(73)×10−27 kg.
Aunified atomic mass unit is equal to one-twelth the mass of a carbon-12 atom.
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.
The atomic mass unit is equal to 931,494 061(21) eV/c2.
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.
Neutrons and protons have masses approximative equal to one amu.

atomic mass unit is equal to one-twelfth of the mass of a carbon-12 atomic mass is equal to one-twelfth of the mass of a carbon-12Atomic Mass is equal to the number of protons and neutrons.

yes i guess so

The mass of proton is only approx. equal to 1 amu.
The proton and the neutron each have a mass approximately equal to one atomic mass unit.
