How to convert atomic units of length to spans (cloth)
1 a.u. of length is equal to 2.31486094 × 10⁻¹⁰ spans (cloth), and 1 span (cloth) is equal to 4,319,913,921 atomic units of length. To convert, multiply by the conversion factor:
spans (cloth) = atomic units of length × 2.31486094 × 10⁻¹⁰
spans (cloth) = atomic units of length ÷ 4,319,913,921Example: convert 1 a₀ to span: 1 × 2.31486094 × 10⁻¹⁰ = 2.31486094 × 10⁻¹⁰ span.
