Convert Kilometers to Meters
Kilometers to meters is the most basic metric length conversion there is — both units are metric, and one kilometer is exactly 1,000 meters. It's the conversion behind every race distance, road sign, and map scale.

The conversion factor
One kilometer equals exactly 1,000 meters. Since both are metric units built on powers of ten, there's no rounding involved — it's a clean multiplication.
meters = kilometers × 1,000
For example, 5 km = 5,000 m, 10 km = 10,000 m, and 100 km = 100,000 m.
When you'd use it
This is the conversion behind race distances (a "5K" is 5,000 meters), map scales, and pretty much any everyday situation where a distance needs to switch between the two most common metric length units. Because the factor is just a shift of the decimal point, most people do this one in their head without needing a tool — but it's handy to have a definitive answer when the number gets long or precision matters.
Frequently asked questions
How many meters are in a kilometer?
Exactly 1,000 meters. The kilometer is defined as 1,000 meters, so this conversion carries zero rounding error.
Is the kilometers to meters conversion exact?
Yes. Both units are part of the metric system, and the kilometer is literally defined as a multiple of the meter — exactly 1,000 of them.
What's a quick way to convert kilometers to meters?
Just move the decimal point three places to the right. A 5K run is 5,000 meters, and a 10K run is 10,000 meters.
