Definition of mile (Roman) unit

The Roman mile (mille passus, meaning “thousand paces”) was a unit of length equal to 1,000 double paces, or approximately 1,478.5 meters. It measured distances in Roman roads, military routes, and land surveys.

History of mile (Roman) unit

The Roman mile developed from the Roman pace, a double step traditionally associated with military marching. Its Latin name, mille passus, literally means “a thousand paces.” Because the pace was standardized for practical administration, the mile became an important distance measure during Rome’s expansion. Roman roads commonly used milestones (miliaria) to mark distances from cities or provincial boundaries. The unit was not perfectly identical everywhere, but it is generally estimated at 5,000 Roman feet, approximately 1,478.5 meters. Medieval and later European measures sometimes preserved or adapted its name.
