Conversion Formula
The formula to convert kilometers to miles is: miles = kilometers * 0.621371. This works because 1 kilometer equals approximately 0.621371 miles. Multiplying the kilometer value by this factor scales the distance into miles, aligning metric with imperial measurements.
For example, 40 km x 0.621371 = 24.85484 miles. Each kilometer is multiplied by the ratio to get the equivalent miles. This method ensures accurate conversion based on the fixed ratio between the units.
Conversion Example
- Convert 50 kilometers:
- Start with 50 km.
- Multiply 50 by 0.621371.
- 50 x 0.621371 = 31.06855 miles.
- Result: 50 km is about 31.0686 miles.
- Convert 10 kilometers:
- Start with 10 km.
- Multiply 10 by 0.621371.
- 10 x 0.621371 = 6.21371 miles.
- Result: 10 km is roughly 6.2137 miles.
- Convert 100 kilometers:
- Start with 100 km.
- Multiply 100 by 0.621371.
- 100 x 0.621371 = 62.1371 miles.
- Result: 100 km equals approximately 62.1371 miles.
