"10 kilometres" redirects here. For the long-distance running event, see 10,000 metres.
To help compare different orders of magnitude this page lists lengths between 10 and 100 kilometres (104 to 105 metres). The myriametre (10,000 metres) is a deprecated unit name; the prefix myria- is obsolete, not included among the prefixes when the International System of Units was introduced in 1960.
