How to convert
To go from kilometers to miles, divide by 1.609 (or multiply by 0.6214): 10 km ÷ 1.609 ≈ 6.21 mi. For the reverse, multiply by 1.609. The mile is defined as exactly 1.609344 km.
Handy landmarks
A 5K run is 3.11 miles and a 10K is 6.21 miles; a marathon (42.195 km) is 26.22 miles. A quick mental shortcut: multiply km by 0.6 for a rough mile figure, or take miles × 1.6 for km — close enough for directions, though not for precise work.
