Angstrom

A unit of length, 1 ångström (1 Å) equals 10^-10 meters or 0.1 nanometers. It is named after the Swedish physicist Anders Jonas Ångström. This unit is often used for measuring the diameters of atoms, which are typically around two to three Å. For a list of objects of size 1 to 10 Å, see 1e-10 m.
