What is the Bohr radius used for?

The Bohr radius serves as an atomic unit of length important in quantum chemistry, atomic-structure calculations, and computational physics.

What was the Roman actus used to measure?

The Roman actus was an ancient length unit used in Roman land measurement, cadastral surveying, and to define area units like the actus quadratus.

Why convert from Bohr radius to Roman actus?

Converting from Bohr radius to Roman actus helps relate atomic-scale distances to historical land measurement units for educational, archaeological, or interdisciplinary research.
