angstrom (Å)

[ang′strəm]
Etymology: Anders Jonas Angström, Swedish physicist, 1814-1874
a unit of measure of length equal to 0.1 nanometer (1/10,000,000,000 meter), or 10-10 meter. Also called angstrom unit.

Å

angström

A non-SI (International System) unit of length equal to 10-8 cm, or 10-10 m, which was formerly used to measure molecules.

Å

Abbreviation for angstrom;Ångström unit.

[A.J. Ångström]

angstrom or angstrom unit (Å or A)

a measurement of length, equal to one ten thousandth of a MICRON. Nowadays, objects of such size are measured in nanometres (10-9m), where 1Å = 0.1 nm.

Ångström,

ångström - a unit of wavelength, 10-10 m, roughly the diameter of an atom; equivalent to 0.1 nm. Synonym(s): Ångström unit
Ångström law - a substance absorbs light of the same wavelength as it emits when luminous.
Ångström scale - a table of wavelengths of a large number of light rays corresponding to as many Fraunhofer lines in the spectrum.
