Laachtjuar

At laachtjuar as en miat för't lengde. Hat woort uun a astronomii brükt för grat waier. At laachtjuar as di wai, di det laacht uun ian juar skaafet (uun a leesag rüm). Det san 9,46 biljuun kilomeetern. (= 9,46 · 10¹² km). Uk wan diar det wurd juar uun föörkomt, as det laachtjuar nian miat för't tidj.
