1 m = 0.001 km (meter → kilometer)
1 m = 0.001 km
1 meter equals 0.001 kilometers. To convert meters to kilometers, multiply the meter value by 0.001. For quick reference: 1 m = 0.001 km, 5 m = 0.005 km, 10 m = 0.01 km, 100 m = 0.1 km.
Kilometers = Meters × 0.001Metres to kilometres divides by 1000. A 1500 m middle-distance race is 1.5 km; the 50 m world record for freestyle swimming is 0.05 km, which is why nobody quotes it that way. The conversion is decimal and exact. Use it to scale up athletics times into travel-scale distances, or to express GPS-track segments in a more readable unit. SI prescribes the kilometre as the standard for distances above a few hundred metres.
Start with your value in meters.
Multiply the meter value by 0.001. This is the exact conversion factor from meters to kilometers.
The product is your value in kilometers. For example, 5 m × 0.001 = 0.005 km.

The meter (m) is the SI base unit of length. Defined since 2019 as the distance light travels in vacuum in exactly 1/299,792,458 of a second, the meter is the reference all other length units derive from. It is the standard unit for room dimensions, sports fields, and short-to-mid distances in most of the world.
The kilometer (km) equals exactly 1,000 meters. It is the standard unit for road distances in almost every country except the United States and the United Kingdom. A 5K running race is 5 kilometers; a marathon is 42.195 km.
