What is a gigameter used for?

A gigameter is an SI derived length unit equal to one billion metres, typically used to express vast distances such as those between planets in our Solar System.

What is the Roman actus?

The Roman actus is an ancient Roman length unit about 35.5 metres, historically applied in land surveying and defining property boundaries.

Why convert gigameters to Roman actus?

Converting gigameters to Roman actus helps relate massive modern astronomical distances to traditional measurements used in ancient Roman surveying and cadastral practices.
