Where the mile to kilometer factor comes from

  1. One statute mile is exactly 1609.344 metres, which is 1.609344 kilometres, derived from 5280 feet at 0.3048 m each.
  2. That constant is the conversion directly.
  3. kilometres = miles × 1.609344. Because the mile is exactly defined, the factor is exact.
  4. So 26.2 miles is 42.16 km, and 100 miles is 160.93 km.

Sources

Common mistakes

Nautical miles convert differently

If your source is a boat or aircraft, the miles are probably nautical (1.852 km each), not statute (1.609344 km). Ten nautical miles is 18.52 km, not 16.09 km. This page uses the statute land mile.

mph and km/h use the same factor, but per hour

Converting a speed limit works the same way: 60 mph is 96.56 km/h because 60 × 1.609344 = 96.56. The trap is mixing distance and speed in one sum; convert the number first, then reattach the 'per hour'.

To convert miles to kilometers, multiply the number of miles by 1.6093. One mile equals 1.6093 kilometers, and one kilometer equals 0.621371 miles, so the relationship is fixed and exact. As a worked example, 10 mi comes to 16.0934 km. Enter your own figure in the converter above to get an instant answer, or use the swap button to flip the direction. This is a length conversion, and like every tool on UnitGlide it runs locally in your browser with no account or upload required. The table further down shows a range of common mile values already worked out in kilometers, plus the reverse kilometer to mile direction, which is handy for quick reference or double-checking a result by hand.
