Atomic Mass Unit (abbreviations: amu, or u): also known as dalton (symbol: Da), is a standard unit of mass that used on an atomic or molecular scale (atomic mass). One unified atomic mass unit is about the mass of one nucleon (either a single proton or neutron) and equivalent to 1 g/mol.
Gram (abbreviation: gm): is a SI (metric) system unit of mass. Where, at the temperature of melting ice, it is the absolute weight of a volume equal to the hundredth part of a metre cube of pure water.
How to Convert Atomic Mass Units to Grams
Example: How many grams are equivalent to 73.32 atomic mass units?
As;
1 atomic mass units = 1.66E-24 grams
73.32 atomic mass units = Y grams
Assuming Y is the answer, and by criss-cross principle;
Y equals 73.32 times 1.66E-24 over 1
(i.e.) Y = 73.32 * 1.66E-24 / 1 = 1.217112E-22 grams
Answer is: 1.217112E-22 grams are equivalent to 73.32 atomic mass units.
