Conversion Formula
The formula to convert kilometers to miles is: miles = kilometers × 0.621371. This means you multiply the number of kilometers by the factor 0.621371, which is the length of one kilometer expressed in miles.
This works because one kilometer equals roughly 0.621371 miles, a fixed ratio based on the international definition of these units. Converting by multiplication preserves the proportional distance between the two units.
For example, converting 24.7 km to miles step-by-step:
- Start with 24.7 kilometers
- Multiply 24.7 by 0.621371 → 24.7 × 0.621371
- This equals approximately 15.3457 miles
Conversion Example
- Convert 10 km to miles:
- Multiply 10 × 0.621371
- Result: 6.2137 miles
- Convert 5.5 km to miles:
- Multiply 5.5 × 0.621371
- Result: 3.4175 miles
- Convert 42 km to miles:
- Multiply 42 × 0.621371
- Result: 26.0976 miles
- Convert 0.8 km to miles:
- Multiply 0.8 × 0.621371
- Result: 0.4971 miles

Conversion Definitions
Kilometer (km): A kilometer is a metric unit of length equal to 1,000 meters. It is used worldwide for measuring distances between geographical locations. One kilometer is approximately 0.621371 miles in the imperial system, making it common in road signs and maps outside the United States.
Mile: A mile is an imperial unit of length, mostly used in the United States and the UK for measuring longer distances. One mile equals exactly 1,609.344 meters. It subdivides into feet and inches, and is commonly used to describe road distances, racing tracks, and aviation.
Conversion FAQs
Why is the conversion factor 0.621371 instead of a simpler number?
The factor 0.621371 comes from precise definitions of the meter and the international mile. Since both units are standardized, the conversion isn’t a whole number but a decimal reflecting the exact length difference. Using this precise factor ensures accurate conversions across scientific and everyday use.
Can I convert kilometers to miles by dividing instead of multiplying?
You could divide by approximately 1.60934 (the number of kilometers in a mile), but multiplying by 0.621371 is more direct and less error-prone. Both methods give the same results, but multiplication by the smaller decimal is simpler for many calculations.
Does this conversion apply to nautical miles too?
No, nautical miles differ from statute miles. One nautical mile is about 1.852 kilometers, which is longer than the standard mile. The 0.621371 factor only converts kilometers to statute miles, so nautical mile conversion requires a different factor.
Why are some converted values rounded differently?
Rounding depends on the number of decimal places chosen. For clarity or practical use, results are often rounded to 4 decimal places, but scientific applications might need more precision. Rounding affects only the displayed number, not the actual conversion accuracy.
How accurate is the conversion for very large distances?
The conversion is accurate for any distance because it’s based on fixed unit definitions. However, for very large distances like intercontinental measurements, Earth’s curvature and geodetic considerations may affect actual travel distances, but the unit conversion remains reliable.
