Miles
The “Miles” value used in this tool’s formula. Adjust it to see results update live.
kilometers = miles × 1.609344. Statute mile, not nautical.
US road trips and marathon shirts speak miles. Highway signs in most of the world speak km. One mile is 1.609344 km. “Times 1.6” is fine in the car; use the exact factor for a race or a fuel log.

Variable definitions
- value
Miles
The “Miles” field. Default 26.2; typical range 0–100000.
- The conversion (kilometers = miles × 1.609344. Statute mile, not nautical.) does not pick US vs UK gallons, SI vs binary megabytes, or Mach at altitude for you. Read the footnote on the page.
- Nothing here is uploaded for the calculation itself.
Frequently Asked Questions
This is the statute (land) mile. Nautical miles are longer — use the nautical page for charts and aviation.

- Nautical Miles to KilometersCharts, flight plans, and AIS tracks use nautical miles because one nmi is one minute of latitude. That is 1.852 km exactly — longer than a statute mile. Do not drop a flight plan into the land-mile converter.
- Kilometers to MilesA 10K is 6.21 miles. Divide km by 1.609344. US cars still show mpg; European trip computers show L/100 km and km/h. This page is only the distance half — speed has its own converter.
- League to KilometersA league was roughly an hour’s walk, which is why Jules Verne’s 20,000 leagues is a cartoon of distance. This page uses the land league of 3 miles (4.828 km). Sea leagues differ. Read the footnote on your map.
- MPH to km/hMultiply mph by 1.609344. 60 mph is 96.6 km/h, not 100. Rental cars and speed-limit photos fail this constantly. The inverse page is km/h to mph if your dash swapped overnight.
- Square Kilometers to Square MilesCity limits and national parks: divide km² by 2.58999. Los Angeles is about 1,300 km², not a “mile” number until you convert. One km² is 0.386 mi².
- Astronomical Units to KilometersThe IAU 2012 astronomical unit is exactly 149,597,870,700 m — about 149.6 million km. Earth–Sun mean distance sits on that stick. Mars at 1.524 au is not a NASA press-round; it is that constant times 1.524.

A 5K is 5,000 meters, not 5 kilometers on the nose if your watch is sloppy. Divide meters by 1,000. Track races, building plans, and “how far was that hike” all live in this split.
Feet to Meters
Unit Converters
US height, ceiling height, and lumber still arrive in feet. Meter plans do not. One foot is exactly 0.3048 m — not “about a third.” Use this when a listing says 10 ft ceilings and the architect works in meters.
Inches to Centimeters
Unit Converters
Monitor diagonals, waist measurements, and photo prints still come in inches. Clothing charts in Europe come in cm. Multiply inches by 2.54. That factor is exact, not a kitchen guess.
