League to Kilometers Converter
kilometers = leagues × 4.828032 (3 statute miles per league).
A 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.

Unit Converters
- 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.
- 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.
- Light Years to KilometersA light year is a distance, not a birthday. It is how far light travels in one Julian year: about 9.461 trillion km. Proxima Centauri is 4.25 ly, not “four years away in a 747.”
- m/s to km/hMultiply m/s by 3.6. Physics problems live in m/s; dashboards live in km/h. 10 m/s is 36 km/h. A 100 m sprint in 10 s is an average 10 m/s — not a highway speed, just a very committed 36 km/h.
- Meters to KilometersA 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.
- Miles to KilometersUS 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.

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.

Very usable on mobile. Would love a save/export option later, but the math feels solid.
