What Is Roman mile?
A Roman mile is an ancient Roman unit of distance. It was used on Roman roads to show how far people had traveled. One Roman mile is a little shorter than the modern mile we use today.
Definition
The Roman mile was based on the idea of counting steps by a soldier.
- 1 Roman mile equals about 1,480 meters.
- 1 Roman mile equals about 1.48 kilometers.
- 1 Roman mile equals about 0.92 modern miles.
- 1 Roman mile equals about 4,854 Roman feet.
So if you walk a Roman mile, you go a bit less far than one modern mile but more than one and a half kilometers.
History / Origin
The Roman mile comes from the Latin words mille passus, which mean one thousand paces.
A Roman pace was not one small step. It was a double step. The distance from when the same foot hit the ground twice. Roman soldiers would count 1,000 of these paces. That distance became one Roman mile.
The Romans built long stone roads across Europe, North Africa, and parts of Asia. Along these roads they put stone markers called milestones. Each one showed the number of Roman miles from an important city, often from Rome itself.
The unit was created to help army movement, tax collection, trade, and travel across the huge Roman Empire. Over many centuries, small differences in local Roman feet could make the Roman mile slightly longer or shorter in different places.
Symbol & Abbreviation
The Romans did not use modern unit symbols like we do today, but they had short forms on stones and documents.
- On Latin texts the Roman mile often appeared as mille passus or mille passuum.
- On milestones it was often written as MP or M P, showing miles from a starting point.
- In modern books about Rome you may see mp used as a short form for Roman mile.
Today, to avoid confusion with the modern mile, writers usually explain clearly that they mean a Roman mile.
Current Use Around the World
