Kilometer is a unit of length in the metric system equivalent to 1000 meters. Miles is also the unit of length equal to 1760 yards. Example:

```Input: 5.5
Output: 3.418

Input: 6.5
Output: 4.039```

Formula:

```1 kilometer equals 0.62137 miles.
Miles = kilometer * 0.62137
Kilometer = Miles / 0.62137```
