Maille conventionnelle (Fr). Konventionelle Zelle (Ge). Cella convenzionale (It). 慣用単位胞 (Ja). Celda convencional (Sp).
For each lattice, the conventional cell is the cell obeying the following conditions:
- its basis vectors define a right-handed axial setting;
- its edges are along symmetry directions of the lattice;
- it is the smallest cell compatible with the above condition.
Crystals having the same type of conventional cell belong to the same crystal family.
