Kilometer

The kilometre, spelt kilometer in American English, is a unit of length in the International System of Units, equal to one thousand metres. It is now the measurement unit used for expressing distances between geographical places on land in most of the world; notable exceptions are the United States and the United Kingdom where the statute mile is the unit used. The abbreviations k or K are commonly used to represent kilometre, but are not recommended by the BIPM. A slang term for the kilometre in the US, UK, and Canadian militaries is klick.
