Conversion Formula
The formula to convert kilometers into miles is miles = kilometers * 0.621371. This works because a mile is defined as exactly 1.609344 kilometers, so dividing 1 by this number gives the conversion factor. Multiplying kilometers by 0.621371 converts to miles directly.
For example, if converting 50 kilometers: 50 * 0.621371 = 31.06855 miles. This step-by-step calculation confirms the process of changing metric to imperial distance units.
Conversion Example
- Convert 80 kilometers:
- Step 1: Write down the value in km (80 km).
- Step 2: Multiply 80 by 0.621371 to get miles.
- Step 3: 80 * 0.621371 = 49.70968 miles.
- Step 4: The answer is approximately 49.71 miles.
- Convert 25 kilometers:
- Step 1: Write down 25 km.
- Step 2: Multiply by 0.621371.
- Step 3: 25 * 0.621371 = 15.534275 miles.
- Step 4: Rounded answer is 15.53 miles.
- Convert 120 kilometers:
- Step 1: Write down 120 km.
- Step 2: Multiply by 0.621371.
- Step 3: 120 * 0.621371 = 74.56452 miles.
- Step 4: Rounded answer is 74.56 miles.
