An ångström (symbol Å) is a unit of length equal to 10-10 meters, used principally to express the wavelengths of electromagnetic radiation. It is equivalent to 0.1 nanometer. It was named after Anders Jonas Ångström, a Swedish physicist.
Comparative units of length
- While attempting to initialize the transporters aboard USS Voyager, Harry Kim aligned the confinement beam to 10 ångströms. (VOY: "Counterpoint")
- A computer analysis of the Murasaki Effect yielded a radiation wave length of 370 ångströms. (TOS: "The Galileo Seven")
- While analyzing the Cytherian probe, Reginald Barclay noted that the sensors were up visual wavelengths between 4,500 and 7,000 ångströms. (TNG: "The Nth Degree")
