What you are converting

Mile

A mile is a unit of length used in the United States and United Kingdom for road distances; one mile equals 5,280 feet or about 1,609 meters.

Kilometer

A kilometer is a metric unit of length equal to 1,000 meters, the standard distance unit on road signs across most of the world and in races like the 5K.

Why convert and when you would use this

Drivers crossing between the United States and Canada or Mexico must translate road signs and fuel-range estimates between miles and kilometers, while runners tracking workouts often compare mileage logged in miles against race distances such as 5K or 10K events measured in kilometers.

Worked example

To convert 10 miles to kilometers, multiply 10 by 1.609344, which gives 16.09344 kilometers. A driver seeing a 10-mile distance on an American highway can therefore expect roughly 16 kilometers on a European road sign, and a runner logging 10 miles has covered just over 16 kilometers.

Rounding and accuracy

Use two decimal places for travel distances, fuel ranges, and fitness totals, since differences below ten meters are irrelevant at that scale. Keep three or more decimals for engineering, surveying, or aviation work, and round only at the final step after multiplying to avoid compounding errors.
