Meters to kilometers

1 meter = 0.001 kilometers

Type a value in meters (m) to get kilometers (km) straight away. A meter is smaller than a kilometer, so the number goes down. Both units belong to length, measured here against the meter.

FromTo0.001

1 m = 0.001 km

Formula

km = m × 0.001

One meter is 0.001 kilometers, so multiply by that factor. You can also divide by 1,000, the number of meters in one kilometer. Here m is the value in meters and km is the result in kilometers.

Worked example: 25 meters × 0.001 = 0.025 kilometers.

About the units

Meter (m). The SI base unit of length, defined by the distance light travels in 1/299,792,458 of a second.

Kilometer (km). 1,000 meters. Used for road distances and running races outside the US and UK.

Going the other way, 1 kilometer is 1,000 meters.

Questions
