Atoms are too small to weigh directly, therefore their masses are determined indirectly through various methods and ratios. The relative atomic mass scale compares the mass of an atom to a reference standard, which is typically the mass of an isotope of carbon-12. This allows for easier comparison of atomic masses and helps to standardize the measurement.
