What is a Roman actus?

The Roman actus is an ancient unit of length equal to 120 Roman feet, about 35.5 meters, used mainly for land measurement and surveying in Roman times.

What does a.u. of length [a.u., b] represent?

It represents the atomic unit of length or Bohr radius, a fundamental scale in atomic physics equal to the average electron-proton distance in a hydrogen atom's ground state.

Why convert Roman actus to atomic units?

This conversion helps link historical land measurement units with atomic scale distances, aiding interdisciplinary research in quantum physics and the history of measurement.
