What is a Roman actus?

It is an ancient Roman unit of length equal to 120 Roman feet, approximately 35.5 metres, historically used for land measurement and surveying.

What is an exameter [Em]?

An exameter is an SI unit of length equal to 10^18 metres, used to express extremely large distances in astrophysical and cosmological contexts.

Why convert Roman actus to exameters?

To translate historical land measurements into modern scientific units for educational, theoretical, or cosmological studies.
