Kilometers to meters

1 kilometer = 1,000 meters

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

1 km = 1,000 m

Formula

m = km × 1,000

One kilometer is 1,000 meters, so multiply the kilometer value by that factor. Here km is the value in kilometers and m is the result in meters.

Worked example: 42.195 kilometers × 1,000 = 42,195 meters.

About the units

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

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

Going the other way, 1 meter is 0.001 kilometers.

Questions
