Args
wigner_seitz_radius (float): The radius per particle in atomic units. n_particles (int): The number of particles in the simulation cell. dimension (int): The dimension of the system.

Returns
length_scale (float): The length scale for the simulation.

Raises
`ValueError`	System dimension must be a positive integer.
