How to Convert Kilometers to Miles?

1 kilometer is equal to 1/1,609344 miles:

1 km = 1/1,609344 mi = 0,6213711 mi

d(mi) = d(km) / 1,609344, where

d(mi) – distance in miles (mi),

d(km) – distance in kilometers (km).

Example

Imagine you have a high-voltage power transmission line that stretches for 100 kilometers. To determine its length in miles, we can use the following formula:

d(mi) = d(km) * 0.621371 = 100 km * 0.621371 ≈ 62.1371 miles

So, the power transmission line is approximately 62.14 miles long.
