Conversion Formula
The formula to convert kilometers to miles is: miles = kilometers * 0.621371. This works because miles and kilometers are units of distance, with 1 kilometer equal to approximately 0.621371 miles. So, multiplying the number of kilometers by this factor gives miles.
For example, converting 28 km: 28 * 0.621371 = 17.398 miles. Each kilometer is scaled by the conversion rate to find its equivalent in miles, which allows for precise measurements across different systems.
Conversion Example
- Suppose you want to convert 50 kilometers:
- Step 1: Write down the number of kilometers: 50 km.
- Step 2: Multiply by the conversion factor: 50 * 0.621371.
- Step 3: Calculate: 50 * 0.621371 = 31.06855 miles.
- Step 4: The answer is approximately 31.069 miles.
- For 10 kilometers:
- Step 1: 10 km.
- Step 2: 10 * 0.621371.
- Step 3: 6.21371 miles.
- Step 4: Rounded, about 6.214 miles.
- Converting 100 kilometers:
- Step 1: 100 km.
- Step 2: 100 * 0.621371.
- Step 3: 62.1371 miles.
- Step 4: So, 100 km equals roughly 62.137 miles.

Conversion Definitions
A kilometer is a unit of length in the metric system, equal to 1,000 meters, used worldwide for measuring distances in most countries except the U.S. and a few other places.
Miles are imperial and US customary units of distance, where one mile is exactly 1,609.344 meters, traditionally used in the United States and UK for measuring longer distances and travel routes.
Conversion FAQs
Why is the conversion factor 0.621371 used for kilometers to miles?
This factor is derived from the exact length of a mile in meters, which is 1,609.344 meters. Dividing 1,609.344 meters by 1,000 gives the kilometer equivalent, and then converting meters to miles: 1 mile = 1,609.344 meters, so 1 km = 1,000 / 1,609.344 ≈ 0.621371 miles.
Can I use this conversion for miles to kilometers?
No, this specific factor is for kilometers to miles. To convert miles to kilometers, you would multiply by the reciprocal, approximately 1.60934. Different formulas are needed depending on the direction of conversion.
How accurate is the conversion factor 0.621371?
The factor is highly precise for practical use, rounded to six decimal places. For extremely precise scientific calculations, more decimal places might be used, but for everyday purposes, this value is sufficiently accurate.
Is there a quick way to estimate kilometers in miles without a calculator?
Yes, by approximating: multiply kilometers by 0.62 to get an estimate in miles. For example, 28 km * 0.62 ≈ 17.36 miles, close to the exact 17.398 miles. For rough calculations, this approximation works well.
