Kilometre
*** Shopping-Tip: Kilometre
A '''kilometre''' (
American English American spelling: '''kilometer'''), symbol: '''km''' is a
physical unit unit of
length in the
metric system equal to 1 000
metres (from the
Greek language Greek words ''χίλια'' (''khilia'') = thousand and ''μÎÏ„Ï?ο'' (''metro'') = count/measure). It is approximately equal to 0.621
miles, 1 094
yards or 3 281
Foot (unit of length) feet.
Slang terms for kilometre include "
klick" (sometimes spelt "click" or "klik") and "kay" (or "k"). These non-standard terms can also refer to
kilometre per hour kilometres per hour.
Metric system
:''Main articles:
Metric system and
Metre''
Like the kilometre, all units of length in the metric system are based on the metre, by adding an
SI prefix that stands for a power of ten, such as ''hecto'' for one hundred to form
hectometre (0.1 kilometre) or ''mega'' for one million to form
megametre (1 000 kilometres).
The metre is not only the basis for all units of
length in the metric system, but also of units of
area (the
square metre) and
volume (the
cubic metre). This extends to the kilometre, so one can have square and cubic kilometres.
Unicode has symbols for "km" (㎞), for square kilometre (㎢) and for cubic kilometre (㎦); however, they are useful only in
CJK texts, where they are equal in size to one
Chinese character.
Pronunciation
In theory, the pronunciation of the word ''kilometre'' should have the stress placed on the first syllable, in line with other metric prefixes (as in ''
kilogram'', ''
Joule kilojoule'' and, analogous, ''
kilobyte''). However, pronunciation with the stress on the second syllable is usual in
English language English.
