Topic: Tell me a short, interesting fact about

One fascinating fact about the Roman Empire is that it was the first in the world to have a standardized system of weights and measurements, which greatly facilitated trade and administration across its vast territories. This system, called the Roman weight system, is still used today in some form in many countries. For example, the pound (libra) and the ounce (uncia) trace their origins to the Roman system. Similarly, the mile (milia passuum in Latin) was a unit of distance that was first used by the Romans, and it is still in use today.
