What Does APFU Stand For?

APFU stands for Atoms Per Formula Unit

APFU, or Atoms Per Formula Unit, is a measurement used in chemistry to indicate the number of individual atoms present in a single formula unit of a compound. It plays a crucial role in determining the composition and stoichiometry of chemical substances, facilitating the study of various materials and their properties. APFU is essential for understanding the molecular structure and behavior of compounds, particularly in the fields of crystallography and materials science.
