Unit Converter › Guides › Miles to Kilometers (mi to km)
Convert miles to kilometers with the exact factor defined by NIST (1.609344), a ready table and worked examples.
The international mile is 5,280 feet, and since a foot is exactly 0.3048 m, a mile is exactly 1,609.344 m (1.609344 km).
Kilometers = Miles × 1.609344. To convert miles to kilometers, multiply by 1.609344.

Values are rounded to 3 decimal places for display. The factor itself is exact, so any rounding comes only from the last digit shown.
A marathon of 26.2 mi is 42.165 km (the official distance is 42.195 km, because 26.2 is itself rounded). A speed of 60 mph is 96.561 km/h.
Yes, for the international mile. The old U.S. survey mile was slightly longer, but NIST retired the survey foot at the end of 2022.
