The atomic mass units (amu) are a scale-set to 1/12th the mass of one atom of carbon-12.
They are what you would find as the "atomic mass" of an element on the periodic table.

amu are extremely important because they help us to convert between mass and grams of an element or compound of elements in stoichiometry.
Rule: If you have one mole of any element you have a mass of the amu in grams.
#1 mol#(element A)#=#(amu element A)#grams#

example:
#1 mol (He)=4.003 grams#
