1. What is Distance Conversion?

Distance conversion between miles and kilometers is essential for international travel, navigation, and understanding measurements in different systems. The mile is primarily used in the United States, while most other countries use kilometers.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• 1 mile = 1.60934 kilometers (exact conversion factor)
• The result is rounded to 4 decimal places for precision

Explanation: The conversion factor is based on the international agreement for the exact definition of mile and kilometer.
