Expert Answer:

Atoms being extremely small, cannot be seen or weighted. But by using indirect methods of physics we can calculate absolute mass of all kinds of atoms.
As these masses are too small, it is not convenient touse kilograms or grams as a unit.
Therefore, it is more appropriate to use mass of some standard atom as a unit and then relate the masses of other atoms to it.
Thus resulting atomic masses are called as 'relative atomic masses.'
