Conversion Formula
The formula to convert kilometers to miles is:
Miles = Kilometers × 0.621371
This works because one kilometer is equal to about 0.621371 miles. So when you multiply a number of kilometers by 0.621371, you find out how many miles that distance represents.
For example, converting 28 kilometers:
- Start with 28 km
- Multiply by 0.621371: 28 × 0.621371 = 17.398388
- Result rounded to 4 decimals: 17.3984 miles
This step-by-step calculation shows how the formula works by scaling a kilometer value into miles.

Conversion Definitions
Km (Kilometer): A kilometer is a metric unit of length equal to 1,000 meters. It is used worldwide to measure distances between geographical locations. One kilometer is about 0.621371 miles. Kilometers are common in maps, road signs, and vehicle speed measurements outside of the United States.
Miles: A mile is a unit of length in the imperial and US customary systems equal to 5,280 feet or 1,609.344 meters. It’s mostly used in the United States and the UK for measuring distances on roads and land. Miles are longer than kilometers, so converting between them requires a factor of roughly 0.621371.
Conversion FAQs
Why is the conversion factor 0.621371 used for kilometers to miles?
The factor 0.621371 comes from the precise measurement that one kilometer equals approximately 0.621371 miles. This value is derived from the definitions of both units in meters and feet, ensuring accurate conversion based on their length standards.
Can I convert kilometers to miles by dividing instead of multiplying?
Dividing by the inverse factor works, but it can cause confusion. Since 1 mile is about 1.609344 kilometers, dividing kilometers by 1.609344 converts to miles. However, multiplying by 0.621371 is more direct and less error-prone for km to miles conversion.
Does converting 28 km to miles change with temperature or location?
No, the conversion between kilometers and miles is fixed mathematically and does not vary with physical conditions like temperature or location. It’s a constant ratio based on measurement units.
How precise is the conversion factor 0.621371?
The factor 0.621371 is precise to six decimal places, which is enough for most practical purposes. For extreme precision, more decimal places can be used, but for everyday use, this level of accuracy suffices.
Is there a quick way to estimate miles from kilometers without a calculator?
Yes, a rough estimate is to multiply kilometers by 0.6 or divide by 1.6. This gives a fast but less accurate result, useful for mental calculations when precision is not critical.
