One kilometer is about 0.621371 miles. Multiply kilometers by 0.6214 to get miles; 10 km is about 6.21 miles. This direction is for people who think in miles and meet distances in kilometers: American runners entering a 5K or 10K, travelers driving in Europe or Canada, and hikers following trail signs abroad. It is also useful for reading European property listings that give the distance to the nearest town in kilometers.

Where you’ll use it
Race distances are mostly metric: a 5K is about 3.11 miles, a 10K about 6.21, and a half marathon (21.0975 km) about 13.11. Trail signs and road distances in Canada, continental Europe and Australia are in kilometers. Fitness trackers often let you pick either unit, but route plans, race sites and maps abroad do not, so the conversion comes up before and after the run.
Tip: Multiplying by 0.6 is a common shortcut that reads about 3.4% low. Multiplying by 5 and dividing by 8 (0.625) is much closer, only about 0.6% high.
