Unit System: Non-SI Metric

What is the Angstrom?

The angstrom (or ångström) is a unit of length and is a non-SI but metric accepted unit with the symbol Å.

It is equal in length to one ten-billionth of a metre or 0.1 nanometres (0.1nm).

It is approximately the size of an atom and is mostly used to measure very small distances for example wavelengths of light.

Unit System: Typography

What is the Em?

The em is a unit of length in the field of typography and uses the symbol em.

It is a "relative" unit and equals the currently specified point size. For example, 1 em in a 24-point typeface is equal to 24 points. This allows a typographer to specify text size relative to a base figure.

In metal type, the em was equal to the line height of the metal body. This meant the physical size of the letter could not exceed the em. In digital type, the em is a grid of arbitrary resolution so can be scaled to any point size for screen or print.
