== History ==
TheSutichasqa ångström is named after theångströmmi [[SwedenSuysya|Swedishsuysya llaqta]] [[physicistpachaykamay|pachaykamaq]] [[Anders Jonas Ångström]]manta (1814–1874),[[1814]] onewatamanta of- the[[1874]] founderswatakama) ofkaran, [[spectroscopyispiktrumitriya]].p huk tiksiqninsi.
 
Besides [[astrophysics]], Ångström studied [[heat]] transfer, [[terrestrial magnetism]], and the [[aurora borealis]], which was so prominent for him in his northern skies. He created a spectrum chart of [[solar radiation]] that expresses the [[length]] of [[electromagnetic radiation]] in the [[electromagnetic spectrum]] on the order of multiples of one ten-millionth of a [[millimetre]], or 1{{e|−10}} [[metre]]s. This unit of [[length]] became known as the ångström, Å.

Today, the use of the Ångstrom as a unit is less popular and the nanometre (nm) is often used instead (a metre to the power minus 9 or m -9), the visual region in this case being 400 to 700 nm
 
== Representation in computers ==
[[Unicode]] includes the "angstrom sign" at U+212B (Å). However, the "angstrom sign" is [[Unicode normalization|normalized]] into U+00C5 (Å), and is thereby seen as a (pre-existing) encoding mistake, and it is better to use U+00C5 (Å) directly.
 
When typing “ångström” or “Å”, the following key sequences create the needed characters on various English-language keyboard layouts:
 
[[Microsoft Windows]]
:Å: ALT+0197 (Holding ALT, press and release 0, then 1, then 9, then 7, then release ALT.)
:å: ALT+0229 (Holding ALT, press and release 0, then 2, then 2, then 9, then release ALT.)
:ö: ALT+0246 (Holding ALT, press and release 0, then 2, then 4, then 6, then release ALT.)
 
Alternatively, you can use the "character map" on a Windows computer, found under the Start Menu, Programs, Accessories, System Tools. This program allows you to find a character in one of many different fonts and then copy and paste the character where ever you want to put it.
 
[[Apple Computer|Apple Computer’s]] [[Mac OS]] (including [[Mac OS X]])
:Å: Option-A
:å: Option-a
:ö: Option-u, then o
 
Or, in the Mac OS X, in the “Edit” menu, select “Special Characters…” to open a palette to find and use any character.
