Conversion Formula
To convert kilometers to miles, you use the formula: miles = kilometers × 0.621371. The number 0.621371 is the ratio of one kilometer to miles based on international agreement. Since 1 kilometer is less than 1 mile, the result will always be smaller than the original kilometer value.
For example, converting 24.7 km:
- Multiply 24.7 by 0.621371.
- 24.7 × 0.621371 = 15.3435 miles (rounded to four decimals).
- This means 24.7 km covers a distance of about 15.34 miles.
Conversion Example
- Convert 10 km to miles:
- Multiply 10 × 0.621371 = 6.2137 miles.
- So, 10 km is about 6.21 miles.
- Convert 5.5 km to miles:
- Multiply 5.5 × 0.621371 = 3.4175 miles.
- 5.5 km equals roughly 3.42 miles.
- Convert 100 km to miles:
- 100 × 0.621371 = 62.1371 miles.
- So, 100 km is about 62.14 miles.
- Convert 0.75 km to miles:
- 0.75 × 0.621371 = 0.4660 miles.
- This means 0.75 km is just under half a mile.

Conversion Definitions
Kilometer (km): A kilometer is a metric unit for measuring length or distance, equal to 1,000 meters. It is widely used around the world for road distances and geographical measurements, especially outside the United States. One kilometer equals about 0.621371 miles.
Mile: A mile is a unit of length in the imperial and US customary systems, equal to 5,280 feet or about 1,609.34 meters. It is used primarily in the United States and the UK for distances on roads, running races, and land measurement.
Conversion FAQs
Can I convert kilometers to miles without a calculator?
Yes, you can estimate by multiplying the kilometers by 0.62. This gives a close approximation but less precise than using 0.621371. For example, 24.7 km times 0.62 equals about 15.3 miles, which is very near the exact value.
Why does the conversion factor from km to miles use 0.621371?
This value comes from the international agreement that defines 1 mile as exactly 1,609.344 meters. Since 1 kilometer is 1,000 meters, dividing 1,000 by 1,609.344 gives approximately 0.621371, which is the ratio used for converting lengths.
Is the conversion factor always constant?
Yes, the conversion factor between kilometers and miles is constant because both units are fixed by international standards. The only difference is the unit system (metric vs imperial), so the ratio does not change.
How does negative kilometer value conversion work?
Negative kilometers represent direction or displacement opposite to positive distances. When converting to miles, the negative sign is preserved but magnitude is converted using the same factor. So -0.3 km equals about -0.1864 miles.
