To help compare different orders of magnitude this page lists lengths between 10 and 100 kilometres (104 to 105 metres). The myriametre (sometimes also spelled myriameter, myriometre and myriometer) (10,000 metres) is a deprecated unit name; the decimal metric prefix myria- (sometimes also written as myrio-) is obsolete and not included among the prefixes when the International System of Units was introduced in 1960.
