An ångström (symbol Å) was a unit of length equal to 10−10 meters, used principally to express the wavelengths of electromagnetic radiation. It was equivalent to 0.1 nanometer.
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 312 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")
