About converting kilometers to miles
Kilometers to miles is what travelers from metric countries reach for when reading US or UK road signs, race distances, or car odometers.
Since a mile is 1.609344 km, a kilometer is about 0.621371 miles. To convert, multiply kilometers by 0.621. A 5 km run is 3.11 miles, a 100 km/h motorway speed is 62.1 mph, and the 42.195 km marathon comes back to 26.2 miles.
Because the conversion factor is close to 0.6, many people estimate by taking 60% of the kilometer figure. Athletes often memorize that 10 km is 6.21 miles and that a half marathon (21.1 km) is 13.1 miles, since those distances recur in training plans.
- Quick estimate: kilometers × 0.6, then add a little.
- Reverse the Fibonacci trick — 13 km ≈ 8 miles, 8 km ≈ 5 miles.
