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