How to convert atomic units of length to chains (US survey)
1 a.u. of length is equal to 2.630518535 × 10⁻¹² chains (US survey), and 1 chain (us survey) is equal to 380,153,185,300 atomic units of length. To convert, multiply by the conversion factor:
chains (US survey) = atomic units of length × 2.630518535 × 10⁻¹²
chains (US survey) = atomic units of length ÷ 380,153,185,300Example: convert 1 a₀ to ch (US): 1 × 2.630518535 × 10⁻¹² = 2.630518535 × 10⁻¹² ch (US).
