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

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.
