    Result

    This page opens the length converter preset to miles → kilometers. Since 1959 the international mile has been defined as exactly 1,609.344 meters, so kilometers = miles × 1.609344 with no approximation.

    Anchors to remember: 1 mile = 1.61 km, 3 miles ≈ 4.83 km, 10 miles = 16.09 km, a marathon's 26.2 miles = 42.16 km, and 60 miles = 96.56 km — which is why 60 mph feels close to 100 km/h. Five laps of a 400 m track are just short of 1.25 miles.

    This direction is handy for translating US and UK race distances, route planners, hiking guides and car odometer readings into metric. Enter miles on the left; kilometers appear on the right immediately, and the swap button reverses the direction in one click.
