Conversion Formula
The formula to convert kilometers to miles is miles = kilometers * 0.621371. This works because 1 kilometer is exactly 0.621371 miles, a fixed ratio. For example, if you have 5 km, multiply 5 by 0.621371 which equals 3.106855 miles.
Mathematically, it’s a simple multiplication: the number of kilometers is scaled down by the ratio to convert into miles. This ratio is derived from the international agreement on the length of a mile compared to a kilometer.
Conversion Example
- Convert 2 kilometers:
- Multiply 2 by 0.621371, which gives 1.242742 miles.
- This means 2 km equals approximately 1.2427 miles.
- Convert 10 kilometers:
- Multiply 10 by 0.621371, resulting in 6.21371 miles.
- This shows 10 km is roughly 6.2137 miles.
- Convert 0.5 kilometers:
- Multiply 0.5 by 0.621371, which equals 0.3106855 miles.
- Thus, half a kilometer is about 0.3107 miles.
- Convert 25 kilometers:
- Multiply 25 by 0.621371, resulting in 15.534275 miles.
- So, 25 km is approximately 15.5343 miles.
- Convert 0 kilometers:
- Multiply 0 by 0.621371, which stays 0 miles.
- Zero kilometers equals zero miles.
