This km to miles converter turns kilometers into miles as you type. Race distances, road signs abroad, cycling apps and treadmills switch between the two all the time, and the converter gives the exact figure instead of a rough guess. It runs in your browser and spends no credits.
How many miles is a kilometer
One kilometer is about 0.6214 miles. The mile is defined as exactly 1.609344 km, so a kilometer is a bit more than six tenths of a mile. Ten kilometers is 6.2137 miles.
Km to miles formula
Divide the kilometers by 1.609344:
mi = km ÷ 1.609344
The usual shortcut is to multiply by 0.6. It is quick, but it runs a little low: 10 km × 0.6 is 6 miles, while the exact answer is 6.21. Over a 100 km drive that gap grows to more than 2 miles.

Worked example: a running pace
A runner holding 5:00 per kilometer wants the pace per mile. One mile is 1.609344 km, so multiply: 5 × 1.609344 = 8.0467 minutes, about 8 minutes 3 seconds per mile. A 6:00 per km pace becomes 9.656 minutes, about 9 minutes 39 seconds per mile. The same factor turns a 5K into 3.11 miles and explains why the half marathon is called 13.1.
Driving abroad
A road sign that says 80 km to the next town means 49.71 miles. In the converter you can type any figure from a sign or a map and read it immediately, or press swap to plan a trip in kilometers from a mileage you know.
