How to convert atomic units of length to chains
1 a.u. of length is equal to 2.630523796 × 10⁻¹² chains, and 1 chain is equal to 380,152,425,000 atomic units of length. To convert, multiply by the conversion factor:
chains = atomic units of length × 2.630523796 × 10⁻¹²
chains = atomic units of length ÷ 380,152,425,000Example: convert 1 a₀ to ch: 1 × 2.630523796 × 10⁻¹² = 2.630523796 × 10⁻¹² ch.

About the chain
Gunter's chain is 66 feet (20.1168 m), equal to 100 links or 4 rods. A cricket pitch is one chain long, and an acre is 10 square chains.
