WebThe atomic mass unit (u or amu) is a relative unit based on a carbon-12 atom with six protons and six neutrons, which is assigned an exact value of 12 amu's (u's). This is the standard unit for atomic or molecular mass, and 1 amu is thus 1/12 th the mass of a 12 C atom. This is obviously very small. 1 amu = 1.66054x10-27Kg = 1.66054x10-24 g.
