1 kilometer equals approximately 0.6214 miles.
This conversion is based on the fact that one mile is exactly 1,609.344 meters, and since one kilometer is 1,000 meters, dividing 1,609.344 by 1,000 gives the miles equivalent in kilometers.
Conversion Result and Explanation
Converting 1 kilometer to miles results in about 0.6214 miles, because 1 km = 1,000 meters and 1 mile = 1,609.344 meters. Dividing meters in a mile by meters in a kilometer gives the miles in 1 km, which is roughly a little over half a mile.

Conversion Formula
The formula to convert kilometers to miles is miles = kilometers * 0.621371. This works because 1 kilometer equals 0.621371 miles, based on the exact length of a mile in meters divided by a kilometer in meters. For example, 5 km * 0.621371 = 3.10686 miles.
Conversion Example
- Convert 2 kilometers:
- Multiply 2 by 0.621371.
- 2 * 0.621371 = 1.242742 miles.
- So, 2 kilometers is approximately 1.2427 miles.
- Convert 0.5 kilometers:
- Multiply 0.5 by 0.621371.
- 0.5 * 0.621371 = 0.310686 miles.
- Therefore, half a kilometer equals about 0.3107 miles.
- Convert 10 kilometers:
- Multiply 10 by 0.621371.
- 10 * 0.621371 = 6.21371 miles.
- Thus, 10 km is roughly 6.2137 miles.
