A unit of measure of wavelength equal to 10-10 meter, 0.1 nanometer, or 10-4 micrometer, no longer widely used nor recognized in the SI system of units.

A unit of length named for A.J. Angstome, a Swedish spectoscopist, used in measuring electromagnetic radiation equal to 0.000,000,01 centimeters.

(A) A unit of linear measure equal to 10(-10)m, or 0.1 nm; not an accepted Si unit, but still sometimes used for small distances such as interatomic distances and some wavelengths.

A unit of measurement of the length of light waves. It is equal to 1/10 of a millimicron, or one ten-millionth of a millimeter. There are approximately 254,000,000 Angstrom units in an inch.

Unit of length employed to measure wave lengths of light. One Angstrom unit is one ten-thousandth of a micrometer or one ten-billionth of a meter. Ten Angstrom units make one nanometer.

One ten billionth of a meter; one tenth of a nanometer, abbrev. Å.

A unit of length equal to 10-10 meters or 10-8 centimeters or 3.937 X 10-9 inches or .0001 microns. The symbol for the angstrom unit is Ã….
