How to convert miles to stadia

To convert miles to stadia, multiply the number of miles by 8.382. This factor is exact. To go the other way, multiply stadia by 0.1193032689 (rounded).

stadia = miles × 8.382

Example: 10 miles = 83.82 stadia.

About these units

Mile (mi)

US & ImperialCurrent unit

5,280 feet or 1,760 yards, exactly 1,609.344 meters. This is the statute (international) mile used on US and UK roads.

A thousand paces gave the mile its name. It descends from the Latin mille passus, the Roman mile, by way of Old English mil and Middle English myle. For centuries after Rome, miles of many lengths coexisted; a sixteenth-century Mercator map, for example, shows small, medium and large Flemish miles on a single scale bar. The English statute mile was fixed by an Act of Parliament under Elizabeth I in 1593, which declared that a mile contains eight furlongs, or 5,280 feet.

The 1959 international yard and pound agreement made that mile exactly 1,609.344 meters. A slightly longer US survey mile, about 1,609.347 meters, lingered in American land surveys and was slated for retirement from 1 January 2023. Today the mile is the road unit of the United Kingdom, the United States, Liberia and Myanmar, along with several territories such as the Bahamas, Belize, Guam and the US Virgin Islands. In Canada it survives chiefly in rail transport and horse racing.

1 mile = 1,609.344 meters (exactly).

Stadion (stad)

Ancient GreekHistorical unit (no longer in standard use)Approximate value

The length of the footrace track at Olympia, about 192 m. Other Greek cities used slightly different stadia, from roughly 150 to 210 m.

From the Greek word stadion came the Latin stadium and the English stade, and eventually the stadium where athletes compete. It was the footrace track, and as a distance it was defined, according to Herodotus, as 600 Greek feet. Because the foot differed between cities, the stadion did too. The Olympic version is put at about 192 m, which one table describes as 200 Heracles steps, a proposal from Carl Lehmann-Haupt in 1929.

Estimates for other stadia show how loose the unit is. A figure near 185 m is the most common convergence for the Ptolemaic or Attic stadion, while Babylonian-Persian and Phoenician-Egyptian values reach about 196 and 209 m, and an itinerary stadion near 157 m has been argued for road distances. The overall range is roughly 150 to 210 m. The choice matters for judging Eratosthenes' measurement of the Earth. Eight stadia made a Roman mile, and the medieval stadium came to mean the furlong, about 201 m in modern terms.

1 stadion = 192 meters (approximately).
