Conversion Formula
The conversion formula from kilometers to miles multiplies the number of kilometers by 0.621371. This number is derived from dividing 1 mile (1609.34 meters) by 1 kilometer (1000 meters), which results in approximately 0.621371 miles per kilometer. For example, 1 km * 0.621371 = 0.621371 miles.
Conversion Example
- Convert 2 kilometers:
- Start with 2 km.
- Multiply 2 by 0.621371.
- 2 * 0.621371 = 1.242742 miles.
- This means 2 km equals approximately 1.2427 miles.
- Convert 5 kilometers:
- Start with 5 km.
- Multiply 5 by 0.621371.
- 5 * 0.621371 = 3.106855 miles.
- So, 5 km is about 3.1069 miles.
- Convert 0.5 kilometers:
- Start with 0.5 km.
- Multiply 0.5 by 0.621371.
- 0.5 * 0.621371 = 0.310686 miles.
- Thus, half a kilometer equals around 0.3107 miles.
