What is the US survey chain unit?

The US survey chain is a traditional length unit equal to 66 US survey feet, historically used in U.S. land surveying and subdivided into 100 links.

What does the atomic unit of length represent?

The atomic unit of length, or Bohr radius, corresponds to the mean electron-proton separation in a hydrogen atom and is used in atomic-scale physics calculations.

Why convert chains to atomic units of length?

Conversion helps bridge historical land surveying measurements with atomic-scale units used in quantum mechanics and computational physics for interdisciplinary research.
