Conversion Formula
The formula to convert kilometers to miles is:
miles = kilometers × 0.621371
This formula works because one mile is equal to approximately 1.60934 kilometers, so conversely one kilometer equals about 0.621371 miles. To convert from km to mi, the distance in kilometers is multiplied by this factor.
Example calculation:
- Start with 0.9 km
- Multiply 0.9 by 0.621371: 0.9 × 0.621371 = 0.5592339
- Rounded to 4 decimal places, result is 0.5592 mi
Conversion Example
- Convert 5 km to mi:
- 5 × 0.621371 = 3.106855 mi
- Rounded: 3.1069 mi
- Convert 12.3 km to mi:
- 12.3 × 0.621371 = 7.643857 mi
- Rounded: 7.6439 mi
- Convert 0.05 km to mi:
- 0.05 × 0.621371 = 0.0310685 mi
- Rounded: 0.0311 mi
- Convert 20 km to mi:
- 20 × 0.621371 = 12.42742 mi
- Rounded: 12.4274 mi

Conversion Definitions
Kilometer (km): A kilometer is a metric unit of length equal to 1,000 meters. It is widely used around the world, especially outside the US, to measure distances like road lengths and travel distances. The kilometer is part of the International System of Units (SI).
Mile (mi): A mile is a unit of distance used primarily in the United States and the UK, equal to 5,280 feet or about 1,609.34 meters. Miles are often used for road distances, mile markers, and in some sports measurements like running tracks.
Conversion FAQs
Why does 1 kilometer equal about 0.621371 miles?
This comes from the exact length definitions of each unit. Since 1 mile equals approximately 1,609.34 meters and 1 kilometer is 1,000 meters, dividing 1,000 by 1,609.34 gives about 0.621371. So, multiplying kilometers by this factor converts them into miles.
Can I convert kilometers to miles by dividing instead of multiplying?
Dividing kilometers by 1.60934 will also convert km to miles because 1 mile equals 1.60934 km. Multiplying by 0.621371 or dividing by 1.60934 gives the same result. But multiplication by the decimal is more common in quick calculations.
Why might small errors occur when converting?
Rounding the conversion factor or the final result can cause minor inaccuracies. Also, inputting values with limited decimal places reduces precision. For everyday use, these minor differences are usually negligible.
Are kilometers and miles measuring the same type of distance?
Yes, both measure linear distance or length. The difference lies in their unit systems: kilometers belong to metric system, miles to imperial system. This affects their size but not what they measure.
Is the conversion factor always exactly 0.621371?
The factor 0.621371 is a rounded value based on exact definitions. The actual exact factor extends beyond six decimal places but this level of precision is enough for most practical purposes.
