Convert Meters to Kilometers
1 meter is 0.001 km. One meter is exactly 0.001 kilometers.
One meter is 0.001 kilometers. To convert meters to kilometers, multiply by 0.001; to go the other way, divide by 0.001 or multiply by 1000. The factor is exact rather than rounded: it follows from NIST. The SI base unit, defined since 1983 by the distance light travels in 1/299,792,458 of a second.

Factors are entered by hand from NIST rather than derived from a units library, so the ones that terminate are exact rather than rounded.
The same converter answers this pair however it is written: metres to kilometres is the British spelling of the same units — the metre and the litre are spelled that way outside the United States and the quantity does not change.
How do you convert meters to kilometers? The converter and the working
- 1.Take the measurement in meters.
- 2.Multiply by 0.001 — that is how many kilometers fit in one meter.
- 3.To go back the other way, divide by 0.001, or multiply by 1000.
Worked example: 25 meters to kilometers
- Formula
- m × 0.001 = km
- Arithmetic
- 25 × 0.001 = 0.03 km
- Answer
- 25 m = 0.03 km
The factor is exact, so this figure is exact too — only the display is rounded.

What is a meter?
The SI base unit, defined since 1983 by the distance light travels in 1/299,792,458 of a second.
What is a kilometer?
One thousand meters, and about 0.621 miles.
How many kilometers are in a meter?
One meter is 0.001 kilometers, exactly. Going the other way, one kilometer is 1000 meters. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
