About the meter and the kilometer
The meter (metre) is the SI base unit of length. Since 1983 it has been defined by the speed of light: the distance light travels in a vacuum in 1/299,792,458 of a second. It is used for room sizes, running tracks, swimming pools and building heights almost everywhere outside the US.
A kilometer (kilometre) is 1,000 meters and the standard road-distance unit in most countries. A brisk walker covers about 5 km in an hour, and popular race distances are 5 km, 10 km, the half marathon (21.0975 km) and the marathon (42.195 km).
One kilometer equals 1,000 meters, which makes the kilometer the longer unit of the two.

Meters to kilometers FAQ
How many kilometers are in one meter?
One meter equals exactly 0.001 kilometers. In the other direction, one kilometer equals 1,000 meters.
How do I convert meters to kilometers without a calculator?
convert 120 meters to kilometers. Using kilometers ← meters ÷ 1,000, we get 120 × 0.001 = 0.12 km. To check the result, convert back: 0.12 km ÷ 0.001 = 120 m. For a quick estimate, round the factor to 0.001. Then 120 m is about 0.12 km, compared with the exact 0.12 km (an error of 0%). That is close enough for planning, but use the calculator above when the number matters.
What is an Olympic swimming pool in kilometers?
An Olympic swimming pool is about 50 meters, which is 0.05 kilometers. Treat that as an approximate everyday figure rather than an official measurement.
Are the meters and kilometers the same in every country?
The meter is defined from the speed of light, so it is identical worldwide. The kilometer is exactly 1,000 m.
