The siriometer is a rarely used and an obsolete astronomical unit of length, defined to be equal to about one million astronomical units (au). One siriometer is approximately 149.6 petametres; 4.848 parsecs; 15.8 ..more definition+
Alen or aln is a traditional Scandinavian unit of distance similar to the north German elle: roughly 60 centimeters. The Danish alen, also used in Norway, was equal to 62.77 centimeters (2 Danish fod). The Swedish aln was 59.38 centimeters.
