Miles and Kilometers
One international mile equals exactly 1.609344 kilometers. To convert miles to kilometers, multiply the mile value by 1.609344. A 10-mile distance is therefore 16.09344 kilometers, often rounded to 16.09 km. This conversion is useful for road distances, race lengths, maps and travel planning. Remember that a nautical mile is a different unit and should not use the same factor. When converting a route estimate, the mathematical distance conversion does not account for changes in the actual route, map projection or measurement method. Keep additional decimals for technical work and round only the final value to the level appropriate for the context. For everyday travel, two decimal places are usually more precision than the underlying route estimate requires.
Conversion Formula and Context
One mile equals exactly 1.609344 kilometers. Multiplying miles by 1.609344 gives kilometers; keep extra digits internally when chaining the result into another calculation.
