How It Works
Kilometres (km) are the standard unit for road distances in most of the world. Miles (mi) are used in the United States, United Kingdom (for road speeds), and a few other countries.
Conversion Factor: 1 mile = 1.60934 kilometres. 1 kilometre = 0.621371 miles.
KM to Miles: miles = km × 0.621371. Example: 100 km × 0.621371 = 62.14 miles.
Miles to KM: km = miles × 1.60934. Example: 26.2 miles (marathon) × 1.60934 = 42.16 km.
A useful mental shortcut: 1 mile ≈ 1.6 km, or 5 miles ≈ 8 km.
