General Information

Unit systemmetric
Unit ofLength

Kilometre is a unit of length in the metric system, equal to one thousand metres (kilo- being the SI prefix for 1000). 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.


A millimeter is the smallest unit. There are 10 mm in one centimeter, if an object is smaller than one centimeter, you would use millimeters. A scientist measuring something under a magnifying glass might use millimeters to represent a tiny specimen.
