Kilometer

Definition: A kilometer (symbol: km) is a unit of length in the International System of Units (SI). One kilometer is equivalent to 0.6214 miles.

History/origin: The prefix kilo- is a metric prefix indicating one thousand. One kilometer is therefore one thousand meters. The origin of the kilometer is linked to that of the meter, and its current definition as the distance traveled by light in 1/299 792 458 second. This definition is subject to change, but the relationship between the meter and the kilometer will remain constant.

Current use: It is currently the official unit of measurement for expressing distances between geographical places on land in most of the world. However, there still remain a number of countries that primarily use the mile instead of the kilometer including the United States and the United Kingdom (UK). Unlike the United States, the UK has adopted the metric system; while the metric system is widely used in government, commerce, and industry, remnants of the imperial system can still be seen in the UK's use of miles in its road systems.

Meter

Definition: A meter, or metre (symbol: m), is the base unit of length and distance in the International System of Units (SI). Currently, the meter is defined as the distance traveled by light in 1/299 792 458 of a second.

History/origin: Originally, in 1793, the meter was defined as one ten-millionth of the distance from the equator to the North Pole. This changed in 1889, when the International prototype metre was established as the length of a prototype meter bar (made of an alloy of 90% platinum and 10% iridium) measured at the melting point of ice. In 1960, the meter was again redefined, this time in terms of a certain number of wavelengths of a certain emission line of krypton-86. The current definition of the meter was adopted in 1983.

Current use: Being the SI unit of length, the meter is used worldwide in many applications such as measuring distance, height, length, width, etc. The United States is one notable exception in that it largely uses US customary units such as yards, inches, feet, and miles instead of meters in everyday use.

Possible future changes: The definition of some SI base units may change in the near future. The International Committee for Weights and Measures (CIPM) has proposed re-definition of some of the SI base units in an attempt to further improve the system. Although the definitions of some units may change, the actual size of the units would remain the same; the change in definition will not have much (if any) effect on the daily use of these units.

The meter is one of the units that is being considered for another re-definition. Currently it is based on the length of the path travelled by light in a vacuum during a specific time interval, noted above. If changed, the new definition of the meter will be based on defining the fixed numerical value of the speed of light in vacuum as 299,799,458, expressed in units of m·s-1, where the second is defined in terms of cesium frequency.

How to Convert Kilometer to Meter

1 km = 1000 m
1 m = 0.001 km

Example: convert 15 km to m:
15 km = 15 × 1000 m = 15000 m
