Conversion Formula

The formula to convert kilometers to miles is multiplying the number of kilometers by 0.621371. This works because one kilometer equals approximately 0.621371 miles. For example, converting 10 km: 10 * 0.621371 = 6.21371 miles, giving you the mile equivalent of the distance.

Conversion Example

• Suppose you want to convert 50 kilometers:
  • Step 1: Take the number 50 km.
  • Step 2: Multiply 50 by 0.621371.
  • Step 3: 50 * 0.621371 = 31.06855 miles.
  • Result: 50 kilometers is approximately 31.06855 miles.
• Converting 25 km:
  • Step 1: Use the number 25 km.
  • Step 2: Multiply 25 by 0.621371.
  • Step 3: 25 * 0.621371 = 15.534275 miles.
  • Result: 25 kilometers is about 15.5343 miles.
• Converting 60 km:
  • Step 1: Take 60 km.
  • Step 2: Multiply 60 by 0.621371.
  • Step 3: 60 * 0.621371 = 37.28226 miles.
  • Result: 60 kilometers equals approximately 37.2823 miles.
