The formula to convert AMU to grams is:
\[ g = \text{amu} \times k \]
Where:
The atomic mass unit (amu) is a standard unit of mass that quantifies mass on an atomic or molecular scale. One amu is defined as one twelfth of the mass of an unbound neutral atom of carbon-12 in its nuclear and electronic ground state, and it is approximately equal to 1.66053906660e-24 grams. This unit is used to express atomic and molecular weights, making it easier to compare the masses of different atoms and molecules.
