Kilometers to Miles Formula
To convert kilometers to miles, you divide the number of kilometers by 1.609344. This is exactly the same as multiplying by roughly 0.621371.
Miles (mi) = Kilometers (km) ÷ 1.609344
Conversely, to calculate kilometers from miles, you multiply the miles by exactly 1.609344.
Kilometers (km) = Miles (mi) × 1.609344
Example
If a European road sign says your destination is 100 kilometers away:
100 ÷ 1.609344 = 62.1371 miles
Therefore, 100 kilometers is approximately 62.1 miles.
