How to convert ells to atomic units of length
1 ell is equal to 21,599,569,600 atomic units of length, and 1 a.u. of length is equal to 4.62972188 × 10⁻¹¹ ells. To convert, multiply by the conversion factor:
atomic units of length = ells × 21,599,569,600
atomic units of length = ells ÷ 4.62972188 × 10⁻¹¹Example: convert 1 ell to a₀: 1 × 21,599,569,600 = 21,599,569,600 a₀.
