What is a Roman mile?

The Roman mile was an ancient length unit equal to 1,000 double steps or 5,000 Roman feet, approximately 1,480 metres, used historically for measuring distances on Roman roads.

A megameter is an SI derived unit of length equal to one million metres, commonly used for expressing large terrestrial or planetary distances.

Why convert Roman miles to megameters?

Converting Roman miles to megameters helps express ancient distances in modern SI units that are suitable for scientific, archaeological, and large-scale engineering analyses.
