What is the Greek cubit and why is it important?

The Greek cubit is an ancient length unit based on the forearm from elbow to middle finger, used historically to measure structures and artifacts. It is important for interpreting ancient dimensions in modern terms.

What does converting to the Bohr radius achieve?

Converting to the Bohr radius allows expressing lengths in atomic units that are useful for quantum chemistry, computational physics, and spectroscopy where atomic-scale distances matter.

Are conversions between cubits and Bohr radius exact?

The conversion uses a fixed factor, but the original cubit's length varied historically, and Bohr radius is an atomic scale unit, so precision depends on context and usage.
