The kilometre (American spelling: kilometer), symbol km1 is a unit of length in the metric system, equal to one thousand metres and is therefore exactly equal to the distance travelled by light in free space in 1⁄ 299,792.458 of a second.2 It is the conventionally used measurement unit for expressing distances between geographical places in most of the world; notable exceptions are the United States and the United Kingdom where the statute mile is used.
A slang term for the kilometre in the military is klick and in common speech involving distance it is often abbreviated as simply a k (kay).34 5 6

/ˈkɪlɵmiːtər/ KIL-o-mee-tər and /kɨˈlɒmɨtər/ ki-LOM-i-tərThe former pronunciation follows the general pattern in English whereby metric units of measurement are pronounced with the stress on the first syllable, and preserves the pronunciation of metre. It is generally preferred by the BBC, while most scientists use the pronunciation with stress on the second syllable.78 The latter pronunciation, which follows the stress pattern used for the names of measuring instruments (such as micrometer, barometer, thermometer, tachometer and speedometer), is in common usage as well. Kingsley Amis has suggested that this pronunciation (and the American spelling) be reserved for the thousand-measurer, the wall which Herodotus says Xerxes built around a thousand troops so he could count his army.9
When Australia introduced the metric system, the first pronunciation was declared official by the government's Metric Conversion Board. However, the Australian Prime Minister at the time, Gough Whitlam, insisted that the second pronunciation was the correct one because of the Greek origins of the two parts of the word.10

Niagara Falls from Prospect Point Niagara Falls (1039 m)The distance between the American extremity of the Niagara Falls and the Canadian extremity is 1039 m,17 or fractionally over a kilometre. Although the length of the rim of the Canadian extremity (Horseshoe Falls is quoted as being 790 m and the rim of the American extremity American Falls as being 320 m which add up to more than 1110 m, the rim of the Horseshoe falls is far from straight, so the direct distance between the end-points is 304 m.

International usageThe United Kingdom and the United States are the only two developed countries which continue to use miles on road signs.citation needed
United KingdomAlthough road signs in the United Kingdom show distances in miles,1819 location marker posts that are used for reference purposes by road engineers and emergency services are kilometre-based.20 The advent of the mobile phone has been instrumental in the English Department for Transport authorising the use of driver location signs to convey the [kilometre-based] information of location marker posts to road users should they need to contact the emergency services.
United StatesIn the US, the National Highway System Designation Act of 1995 prohibits the use of federal-aid highway funds to convert existing signs or purchase new signs with metric units.21 However, the Manual on Uniform Traffic Control Devices since 2000 is published in both metric and American Customary Units. (See also Metrication in the United States.)
