How to convert kilometers to meters
meters = kilometers × 1,000
1 kilometer is 1,000 meters (SI prefix kilo, 10³). The meter is the SI base unit of length.
The factor is exact in both directions: 1 km = 1,000 m and 1 m = 0.001 km. Nothing is rounded until you choose how many decimals to show.
Worked example: 2.5 km
- Start with the value in kilometers: 2.5 km.
- Multiply by 1,000, because 1 kilometer = 1,000 meters: 2.5 × 1,000 = 2,500 m.
