What is a gram in the International System of Units?

A gram is an SI-derived unit of mass equal to one thousandth of a kilogram, commonly used for measuring small masses.

What does the atomic mass unit represent?

An atomic mass unit is defined as one twelfth of the mass of a neutral carbon-12 atom, serving as a scale for atomic and molecular masses.

Why convert grams to atomic mass units?

Converting from grams to atomic mass units allows expressing macroscopic masses at the atomic or molecular level, useful in scientific analyses.
