Angstrom vs. Micron — What's the Difference?

The angstrom (, ; ANG-strəm, ANG-strum) or ångström is a metric unit of length equal to 10−10 m; that is, one ten-billionth (US) of a metre, a hundred-millionth of a centimetre, 0.1 nanometre, or 100 picometres. Its symbol is Å, a letter of the Swedish alphabet.

A unit of length equal to one millionth of a metre, used in many technological and scientific fields.

A unit of length equal to one ten-billionth (10−10) of a meter, used especially to specify radiation wavelengths. Also called angstrom unit.

A unit of length equal to one thousandth (10-3) of a millimeter or one millionth (10-6) of a meter. Also called micrometer.

(physics) A unit of length equal to 10⁻¹⁰ meters (that is, one ten-billionth of a meter), approximately the size of an atom, and denoted by the symbol Å, used especially to measure the wavelength of electromagnetic radiation or distances between atoms.

(physics) The thousandth part of one millimeter; the millionth part of a meter.

A metric unit of length equal to one ten billionth of a meter (or 0.0001 micron); used to specify wavelengths of electromagnetic radiation

(figurative) A very tiny amount.
