Units of Measure / How Many Meters in a Kilometer

How Many Meters in a Kilometer

It is not difficult to guess that meters1 and kilometers2 are parts of the same measurement system. It is called the International System of Units3, or the metric system. Sometimes it is abbreviated SI from its French name Système international d'unités. Nowadays almost all countries in the world have adopted this system, except the USA, Burma and Liberia, where miles, yards, feet and other unit are used to measure length.

The meter is one of the basic units in the SI. The prefix “kilo” has the Greek origin. It means “thousand” and was first used in 1795 by French scientists. The meaning of the prefix “kilo” will help you to remember how many meters there are in a kilometer.

To convert meters to kilometers, you should divide the number of meters by 1000. If you want to calculate, how many meters there are in several kilometers, multiply km by 1000.

Converting meters and kilometers to length units from non-metric system is not so easy. We hope this table will help you to do it.
