Enter a distance in miles to convert it to kilometers.

Miles and kilometers

Miles and kilometers are the road-distance units that travelers, runners, and drivers swap between most. One mile equals exactly 1.609344 kilometers, so a number in miles is always a little over one and a half times larger in kilometers.

This matters when reading foreign road signs, comparing race distances, or making sense of a car built for another market. The converter works both ways, turning miles into kilometers or kilometers back into miles.
