Symbol Meaning

The angstrom unit is traditionally denoted by the capital letter “A” with a small circle above. It's called “Angstrom Sign Å”. There are two symbols with similar writing in Unicode: the one you see on this page Å , and the Latin capital letter A with a circle Å from the Latin-1 Supplement 0080–00FF block.

Angstrom is a unit of length that is used worldwide. However, it doesn't form a part of the International System of Units (SI). One angstrom is equal to 1 µm (one millionth of a meter). This is approximately the diameter of an electron's orbit, the distance between bonds in a crystalline lattice. As for the SI system, the nearest unit to the angstrom is the nanometer ㎚ .

The symbol “Angstrom Sign” is included in the “Letterlike symbols” subblock of the “Letterlike Symbols” block and was approved as part of Unicode version 1.1 in 1993.
