Conversion Formula
To convert kilometers to miles, you multiply the number of kilometers by a constant factor, 0.621371. This factor represents how many miles are in one kilometer. Because kilometers are longer than miles, the number reduces when converted.
The formula looks like this:
miles = kilometers × 0.621371
For example, converting 180 kilometers:
- Multiply 180 by 0.621371
- 180 × 0.621371 = 111.84678 miles
- Rounded to four decimal places, that is 111.8468 miles
This works because the mile is defined as exactly 1,609.344 meters and the kilometer is 1,000 meters. Dividing 1,000 by 1,609.344 gives the conversion factor 0.621371.
Conversion Example
- Convert 50 km to miles:
- Multiply 50 × 0.621371
- 50 × 0.621371 = 31.06855 miles
- Result: 31.0686 miles (rounded)
- Convert 100 km to miles:
- 100 × 0.621371 = 62.1371 miles
- Result: 62.1371 miles
- Convert 250 km to miles:
- 250 × 0.621371 = 155.34275 miles
- Result: 155.3428 miles
- Convert 5 km to miles:
- 5 × 0.621371 = 3.106855 miles
- Result: 3.1069 miles

Conversion Definitions
Kilometer (km): A kilometer is a metric unit of length equal to 1,000 meters. It is commonly used to measure distances between geographical locations, like cities or countries. The kilometer is part of the International System of Units and is widely used worldwide for road signs and maps.
Mile (mi): A mile is an imperial unit of length that equals 5,280 feet or about 1,609 meters. It is used mainly in the United States and the United Kingdom to measure distances, such as on highways or for running races. One mile is longer than one kilometer.
Conversion FAQs
Why does the conversion factor 0.621371 work for kilometers to miles?
The factor 0.621371 comes from the precise definitions of both units: 1 mile equals 1,609.344 meters, and 1 kilometer is 1,000 meters. Dividing 1,000 by 1,609.344 gives 0.621371. Multiplying kilometers by this converts them into miles accurately.
Can I use the same factor to convert miles back to kilometers?
No, the conversion from miles to kilometers requires a different factor. Since 1 mile equals 1.609344 kilometers, you multiply miles by 1.609344 to get kilometers. The factors for converting back and forth are inverses of each other.
Is the conversion exact or an approximation?
The factor 0.621371 is exact up to six decimal places based on the international agreement on unit lengths. For most practical purposes, this provides an accurate conversion, but rounding may cause tiny differences depending on decimal places used.
What causes small differences in mile values when converting from kilometers?
Differences arise from rounding decimals during multiplication or from using approximate conversion factors. Using more decimal places reduces these differences, but slight variations are common when rounding.
Are kilometers used everywhere instead of miles?
No, kilometers are part of the metric system used mostly worldwide, but miles are still used in countries like the United States and the United Kingdom. This can cause confusion when reading maps or travel distances between countries that use different units.
