What is a Roman mile?

It is an ancient unit of length equal to 1,000 double steps or about 1,480 meters, used historically on Roman roads and surveys.

Why use gigameters for length measurements?

Gigameters measure very large distances such as those in astronomy, making them ideal for interplanetary scales.

Can Roman miles vary between sources?

Yes, because they are based on ancient standards, slight variations in the Roman mile can occur.
