Write a Python program that converts a distance in kilometers to miles.
Example 1
- Input: 5
- Output: 3.106855
- Explanation:
- Step 1: Apply the conversion formula: miles = kilometers × 0.621371.
- Step 2: miles = 5 × 0.621371 = 3.106855.
- Step 3: Return 3.106855 as the result.
Example 2
- Input: 8.5
- Output: 5.281654
- Explanation:
- Step 1: Apply the conversion formula: miles = kilometers × 0.621371.
- Step 2: miles = 8.5 × 0.621371 = 5.281654.
- Step 3: Return 5.281654 as the result (rounded to 6 decimal places).
Constraints
- 0 ≤ kilometers ≤ 10^6
- Use the conversion factor: 1 kilometer = 0.621371 miles
- Round the result to 6 decimal places
- Time Complexity: O(1)
- Space Complexity: O(1)

Solution Hints
- Use the formula: miles = kilometers * 0.621371
- Create a conversion function: def km_to_miles(km): return km * 0.621371
- Use round(): miles = round(kilometers * 0.621371, 6)
- Use f-string formatting: f"{kilometers * 0.621371:.6f}"
