The English word “mile” derives from the Latin “mille passus”, meaning “a thousand paces”. A Roman mile was the distance a soldier would walk in 1000 paces (a pace being two steps, one with each foot).
Over time, the actual distance referred to as a “mile” has changed. The modern English mile is 5280 (modern) feet. The Roman mile is believed to have been about 4,854 (modern) feet.
