Explanation
The angstrom (Aº) is an internationally recognized unit of length and is a part of the metric system. An angstrom or ångström is used to measure very small distances. One angstrom is equal to 10−10 m (one ten-billionth of a meter or 0.1 nanometers). In decimal, it can be expressed as 0.0000000001 meters. The symbol for angstrom is Å, which is a letter in the Swedish alphabet.
