What is a angstrom?
An angstrom is one ten-billionth of a meter, or one tenth of a nanometer. It is named after the Swedish physicist Anders Jonas Ångström, who studied light and the colors given off by gases.
Atoms are a few angstroms across, so chemists and crystallographers use the unit to describe the spacing of atoms in a molecule or a crystal.
In writing, the angstrom is usually shortened to "A". One angstrom is 1.000000e-10 meters, and that ratio is what every figure on this page is built from.
