Conversion Formula
The formula to convert miles into kilometers is: kilometers = miles × 1.60934. It works because the mile is a measurement of distance, and 1 mile is defined as exactly 1.60934 kilometers, a fixed conversion factor. For example, converting 2 miles:
- Multiply 2 by 1.60934
- 2 × 1.60934 = 3.21868 km
- So, 2 miles equal approximately 3.2187 kilometers.
Conversion Example
Let’s convert 4.2 miles to km step-by-step:
- Start with 4.2 miles.
- Multiply 4.2 by 1.60934.
- 4.2 × 1.60934 = 6.763428 km.
- Result approximately 6.7634 km.
Another example, converting 0.75 miles:
- Begin with 0.75 miles.
- Multiply 0.75 by 1.60934.
- 0.75 × 1.60934 = 1.206005 km.
- So, 0.75 miles equals about 1.206 km.
