Meters to Kilometers
The meter is the SI base unit of length, defined by the distance light travels in 1/299,792,458 of a second. A kilometer is 1,000 meters, the standard unit for road distances and speed limits outside the US and UK. 1 m equals 0.001 km, so converting between them is a matter of multiplying by that fixed factor — type any value into the converter below and both sides update instantly as you type.
Both units belong to length, measured here against length's base unit (m) — every other length unit on this site converts through that same reference point, which is why the table below can also be read as a quick cross-check against nearby values.
Formula
km = m × 0.001
m = km × 1,000
Worked example: 5 m × 0.001 = 0.005 km.

Frequently asked
- How many Kilometers in a meter?
- 1 m equals 0.001 km.
- How do I convert Meters to Kilometers?
- Multiply the value in m by 0.001 to get km. The converter above does this instantly as you type.
- Is the conversion exact?
- Yes — Meter and Kilometer are both defined by a fixed conversion factor to length's base unit (m), so the result shown is exact to the precision displayed, not an approximation.
