Converting 1 kilometer equals approximately 0.6214 miles.
This conversion is based on the fact that one kilometer is defined as 1000 meters, and since one mile equals 1609.34 meters, dividing 1000 by 1609.34 gives the miles equivalent.
1 Kilometer to Miles
To convert kilometers to miles, you multiply the number of kilometers by the conversion factor 0.6214. This factor is derived from the relationship that 1 mile equals 1609.34 meters and 1 kilometer equals 1000 meters. Therefore, the formula simplifies the conversion process for any distance in kilometers to miles.

Conversion Formula
The formula to convert kilometers to miles is: miles = kilometers × 0.6214. This works because miles are longer than kilometers, and the factor 0.6214 represents the amount of miles in a single kilometer. For example, 5 km times 0.6214 equals 3.107 miles.
Conversion Example
- Convert 2 kilometers:
- Multiply 2 by 0.6214.
- 2 × 0.6214 = 1.2428.
- So, 2 km equals approximately 1.2428 miles.
- Convert 10 kilometers:
- 10 × 0.6214 = 6.214.
- Therefore, 10 km is about 6.214 miles.
- Convert 0.5 kilometers:
- 0.5 × 0.6214 = 0.3107.
- So, half a kilometer equals approximately 0.3107 miles.
- Convert 20 kilometers:
- 20 × 0.6214 = 12.428.
- Hence, 20 km converts to roughly 12.428 miles.
