Kilometers to Miles (km to mi)
1 kilometer = 0.62137119 miles
How to convert kilometers to miles
mi = km ÷ 1.609344
Example: 5 ÷ 1.609344 = 3.1069, so 5 kilometers = 3.1069 miles.
Runners convert kilometers to miles for race distances: a 5K is 3.11 miles, a 10K is 6.21 miles and a marathon (42.195 km) is 26.22 miles.
A handy shortcut is the Fibonacci sequence: consecutive numbers such as 5 and 8, or 8 and 13, are close to the mile–kilometer ratio, so 8 km ≈ 5 mi and 13 km ≈ 8 mi.
