Miles and kilometers

How the converter works

One international mile is exactly 1.609344 kilometers, and one kilometer is about 0.621371 miles. Type in either box and the other updates as you go.

Pace converts the same way. To go from minutes per kilometer to minutes per mile, multiply by 1.609344. To go the other way, divide. For example, 5:00 per km is about 8:03 per mile, and 9:00 per mile is about 5:35 per km.

Common race distances

• 5K is 3.11 miles
• 10K is 6.21 miles
• Half marathon (21.0975 km) is 13.11 miles
• Marathon (42.195 km) is 26.22 miles

Things worth knowing

• A standard track lap is 400 meters, so four laps is 1600 m, which is about 0.994 of a mile. Many runners call that a mile on the track, and the difference is roughly 9 meters.
• Pace is easier to compare across the world in minutes per kilometer, while the United States and United Kingdom mostly race in miles. This tool keeps both visible.
• For finish times at a given pace, use the pace calculator.
