About Miles and Kilometers
Statute miles are customary land-distance units; kilometers are metric distance units. One international mile is exactly 1.609344 kilometers.
Mile as the source, Kilometer as the result
Use this direction when a road, route, race, odometer, or map distance is stated in statute miles but a metric plan, report, or comparison requires kilometers.
Result unit
Kilometer km
Kilometer is a unit used to measure length.
One kilometer equals 1,000 meters.
Where mile-to-kilometer conversion is useful
Mile-to-kilometer conversion helps with international travel, vehicle and route information, distance-based training, maps, and reports that receive a mile value but require metric notation.
An exact terminating kilometer factor
One international mile equals exactly 1.609344 kilometers. The one-mile result terminates in decimal form; any later rounding should reflect the precision of the original distance.
Confirm which mile the source means
This direction starts with the statute mile. Marine and aviation sources often use nautical miles, which must not be substituted because the two units represent different distances.
How this conversion is verified
The international-mile definition supplies the exact 1.609344-kilometer factor. The same definition powers the interactive result and every generated reference-table value.
Standards used for this conversion
For a quick estimate, multiply miles by about 1.6. Use exactly 1.609344 when the receiving value requires the full defined relationship.
This page converts distance, not road speed. Use the Speed category when the source is miles per hour.
Frequently asked questions
6 answers for this conversion
- How do I convert miles to kilometers?
- Multiply the statute-mile value by exactly 1.609344.
- How many kilometers are in one mile?
- One international statute mile equals exactly 1.609344 kilometers.
- Is the 1.609344 factor exact?
- Yes. It follows from the exact international-mile definition and introduces no unit-conversion approximation.
- Is a nautical mile converted with the same factor?
- No. A nautical mile is a different distance. Select Nautical Mile as the source when the original value is navigational.
- When should I round a mile-to-kilometer result?
- Round after the conversion, using no more precision than the original distance and the receiving task support.
- Does mile-to-kilometer conversion also convert mph to km/h?
- No. Miles and kilometers measure distance. Their per-hour speed units belong to the Speed converter.
