Mile (Roman)

The Roman mile (mille passuum, meaning "a thousand paces") was a unit of distance used in ancient Rome. It measured approximately 1,000 double steps, or 5,000 Roman feet. One Roman foot (pes) was about 11.65 inches (29.6 cm), making the Roman mile roughly 4,850 feet or about 1,480 meters.

The Roman mile was used for measuring distances along roads across the Roman Empire, often marked by milestones (miliaria) placed at intervals of one mile. This system allowed for standardized road construction and efficient communication and transportation across vast territories.

Although shorter than the modern statute mile (1,609.344 meters), the Roman mile laid the foundation for the concept of mile-based distance measurement. The word "mile" itself originates from the Latin "mille," reflecting this Roman origin. Over time, the length of a mile evolved, eventually leading to the modern definitions used today.
