What is a chain in length measurement?

A chain is a traditional surveying unit equal to 66 feet, commonly used historically to measure land and parcels.

What does a.u. of length represent?

An atomic unit of length is the Bohr radius, a fundamental quantum physics length scale used to describe atomic distances.

Why convert chains to atomic units of length?

This conversion helps bridge historical measurement units used in surveying with atomic-scale units used in quantum physics and computational chemistry.
