Convert miles to kilometers instantly with a live calculator, a distance and speed chart, and the manual math.
The US, the UK, and a few other countries measure road distances in miles; the rest of the world uses kilometers. A traveler renting a car abroad, a marathon runner comparing race distances, or someone planning a road trip across a border all hit this conversion. Running and cycling are major triggers: US treadmills and races are often in miles while the same workout data in most apps is logged in kilometers.
Speed adds another layer. A speedometer in mph reading 60 means 96.6 km/h on the European highway. The chart below covers common driving and running distances so you can build a quick instinct: 5 miles is 8 km, 10 miles is 16 km, and 60 mph is about 100 km/h — a coincidence that makes driving conversions easier than most.
