Miles to Kilometers Converter
There are exactly 1.609344 kilometers in one mile. To convert miles to kilometers, multiply by 1.609344.
How to Convert Miles to Kilometers
To convert miles to kilometers, multiply by 1.609344.
For example: 5 miles × 1.609344 = 8.04672 kilometers.
Where This Comes Up
Every American road sign, speed limit and car odometer is in miles, and every one of those numbers has to be converted before it means anything abroad. Runners hit the same wall comparing a 10-mile training run against a 10K race.
The marathon everyone calls 26.2 miles is 42.1648 kilometers, just under the 42.195 km the race is actually defined as — the official distance is metric, and 26.2 is the rounded conversion.
What People Get Wrong
A nautical mile is a different unit entirely: 1,852 meters, about 15 percent longer than a statute mile. Marine and aviation distances use it, so check which mile a figure refers to before converting.

About These Units
The mile
The statute mile is 5,280 feet, or exactly 1,609.344 meters. It is the unit on every American road sign and speedometer. A nautical mile is a different unit of 1,852 meters.
The kilometer
A kilometer is 1,000 meters, a little under two thirds of a mile. Road signs, race distances and car odometers outside the United States are all in kilometers.
Definitions follow NIST Special Publication 811, Appendix B. See how we calculate for the exact values and rounding rules.
Frequently Asked Questions
Is a mile exactly 1.609344 kilometers?
Yes. The statute mile is 5,280 feet and the foot is exactly 0.3048 meters, which makes the mile exactly 1,609.344 meters.
How fast is 60 mph in km/h?
60 miles per hour is 96.5606 kilometers per hour, which is why 100 km/h speed limits feel close to 60 mph.
How many kilometers is a 5-mile run?
5 miles is 8.04672 kilometers, a little over 8K.
Why is 1.6 such a common shortcut?
It is only 0.6 percent off, which is fine for distances and speed limits. Over a marathon it would be out by about a quarter kilometer.
