Miles and kilometers explained
The Mile-to-Kilometer Conversion Factor
One mile equals exactly 1.609344 kilometers. Equivalently, 1 km = 0.621371 miles. The mile here is the international statute mile (5280 feet), defined as exactly 1609.344 meters since 1959. Multiply miles by 1.609 for an everyday conversion.
Where Miles vs Kilometers Splits the World
The US, UK (road signs), Liberia, and Myanmar use miles. Almost every other country uses kilometers. US road signs are in miles per hour and miles of distance; almost every European country shows km/h and km. Driving across borders means switching units mentally.
Reference Conversions
1 mi = 1.609 km. 5 mi = 8.05 km. 10 mi = 16.09 km. 26.2 mi = 42.16 km (marathon distance). 60 mi = 96.56 km. 100 mi = 160.93 km. A 5K race is 3.1 miles; a 10K is 6.2 miles.
Speed Conversions
For speed in mph to km/h, the same factor applies: multiply mph by 1.609. So 60 mph = 96.56 km/h, 70 mph = 112.65 km/h, 100 km/h = 62.14 mph. European highway speed of 130 km/h equals about 81 mph.

10 miles equals 16.09 kilometers.
Is a marathon really 26.2 miles?

What's 60 mph in km/h?
60 mph equals 96.56 km/h. The conversion factor is the same as for distance: 1.609.
How long is a nautical mile?
A nautical mile = 1.852 km, different from a statute mile. Used in aviation, marine navigation, and international maritime law. Not the same as the standard US mile.
Why use km in Europe but miles in US/UK?
Historical convention. Most countries adopted metric (and km) in the 1800s-1900s. The US never formally switched road signage; the UK uses metric for most things but retains miles for roads.
