A twip is a typographic unit equal to 1/20 of a printer's point, used mainly for fine-grained layout in typography and GUI positioning.

What does a.u. of length represent?

The atomic unit of length is the Bohr radius, representing the typical electron–proton separation in a hydrogen atom, widely used in atomic and molecular physics.

Why convert from twips to atomic units?

This conversion helps relate typographic or GUI measurements to atomic-scale distances for physics, chemistry, or computational modeling purposes.
