Cette unité ne fait pas partie du Système international d'unités (SI). Les unités reconnues par le SI, qui peuvent être utilisées à la place de l'ångström sont le picomètre (1 Å = 100 pm) et le nanomètre (1 Å = 0,1 nm). Il semblerait que le picomètre remplace l'ångström pour mesurer les longueurs des liaisons chimiques. 6, record 1, French, - angstr%C3%B6m
