cubic angstrom per particle
Molar volumeexact by definition
A cubic angstrom per particle is 6.02214076 × 10⁻⁷ m³/mol, exact since the Avogadro constant is. Crystallography and atomistic simulation report volume per atom or per formula unit in ų because a unit cell is a few tens to a few hundreds of them; silicon is 20.0 ų per atom.
Watch out: Crystallographic cell volumes in ų are per unit cell, and a cell holds Z formula units. Dividing by Z before converting is the step people forget.
