How to Convert Meter to Kilometer
- 1 m = 0.001 km
- 1 km = 1000 m
- Example: convert 15 m to km: 15 m = 15 × 0.001 km = 0.015 km
Formula
km = m ÷ 1000
Derivation from SI units:
- SI base unit: the distance light travels in vacuum in 1/299 792 458 s
- 1 km = 10³ m
Both units are defined exactly, so the factor is exact. Meter definition: meter; Kilometer definition: kilometer.
Worked examples
- A 5000 m race is 5 km.
5000 m × 0.001 = 5 km - Mount Everest, about 8848 m high, rises 8.848 km above sea level.
8848 m × 0.001 = 8.848 km
